Parker SensoControl Handheld Measuring Devices for Mobile Use: Precise Measurements in Industrial and Mobile Hydraulics

SensoControl handheld measuring devices from Parker are robust, field-ready measuring systems for diagnosing and acquiring data on hydraulic parameters. Designed for service technicians, maintenance personnel, and machine builders, they enable the rapid acquisition of pressure, flow, temperature, and other hydromechanical parameters, as well as their storage and further processing. The devices combine precise sensor signals with universal connection concepts, durable housing materials, and variable evaluation functions, allowing them to be reliably used on construction sites as well as in laboratory environments.

Construction, Materials, and Protection Classes

Housings of SensoControl handheld measuring devices typically consist of impact-resistant, glass-fiber-reinforced plastic or anodized aluminum, combining low weight with high mechanical strength. The front features an impact-resistant display with hardened glass or scratch-resistant polycarbonate; operating elements are usually designed as rubberized buttons that can be operated safely even with gloves. Electrical interfaces and sensor connections are standardized and often designed with IP65/IP67 protection against dust and jet water, making the devices suitable for use in dusty environments, wet areas, and varying weather conditions. Seals on connection sockets and battery compartments are made of NBR or fluorocarbon rubber (FKM) for higher resistance to mineral oils and hydraulic fluids.

Measurement Principles and Accuracy

Parker offers various sensor technologies for different measured variables: piezoresistive pressure sensors for static and dynamic pressure measurements, magnetic-inductive or calorimetric flow sensors for low to medium flow rates, and PT100/NTC temperature sensors for direct media measurement. Pressure ranges typically extend from a few bar to several 1000 bar, depending on the sensor design and measuring adapter. Accuracy specifications typically range between ±0.1% FS and ±1% FS, depending on the sensor class. For applications with high requirements, calibrated sensors with traceable factory calibration are available. Important for selection is knowledge of the maximum system temperature and the media used, as viscosity, temperature, and impurities can influence measurement values.

Connections, Adapters, and Mounting Options

The SensoControl handheld measuring devices are built with a modular connection concept. Common connection standards (DIN, ISO, SAE) are served via quick couplings, screw-in fittings, or measuring hoses. Adapters and rotary screw connections are available in stainless steel (AISI 316) or high-strength brass to ensure galvanic compatibility and corrosion resistance. Seals at connection points use NBR, HNBR, or FKM depending on the medium; for aggressive media or higher temperatures, PTFE seals are available. For mobile applications, flexible, pressure-stable measuring lines with 1/4" or 3/8" connections, as well as short dark hose configurations, are available to reduce vibrations and minimize measurement errors due to hose expansion.

Electrical Interfaces and Data Transfer

SensoControl handheld measuring devices offer digital interfaces for data backup and transfer: USB, Bluetooth, and in some variants, CANopen or Ethernet. The devices store measurement series internally in standardized formats (CSV, TDMS) and support real-time transfer to laptops, tablets, or diagnostic PCs. For mobile data evaluation, apps and PC software are available that enable graphical display, filtering, and export. Signal conditioning (filters, sampling rate, peak detection) can be configured in many devices so that data sets are already usable at the point of use without subsequent processing. Battery life is dimensioned for typical service use; replaceable lithium-ion batteries and fast charging functions allow continuous operation in the field.

Application Areas and Use Cases

SensoControl handheld measuring devices are suitable for direct measurement applications on hydraulic systems, mobile machinery, test benches, and in production lines. They provide precise information about system status, enable leak detection, identification of pressure losses, load flow analysis, and evaluation of pump and valve performance. By combining pressure and flow measurement, volumetric efficiencies can be determined, and fault patterns such as wear on hydraulic pumps or restricted return lines can be quickly identified.

Practical Examples

Example 1 – Service on a Hydraulic Excavator: A technician connects a SensoControl device via quick coupling to the high-pressure line of the main hydraulic circuit. Using the integrated logging function, he records dynamic pressure peaks during slewing, while a second channel simultaneously measures temperature and pump speed. From the data, pressure fluctuations during load changes and decreasing pump efficiency can be identified. After replacing a worn gear pump, a renewed measurement run confirms the restoration of specifications. Example 2 – Plant Commissioning in a Production Line: Before production start, the pressure distribution and flow rate along a hydraulic rail are checked at several measuring points with a SensoControl handheld device. The documentation of the measured values via USB and subsequent analysis in the PC software show an uneven distribution due to a faulty pressure relief valve. After replacement, measurement series are repeated to provide parameter documentation for acceptance. The results are archived for quality assurance and later troubleshooting. Example 3 – Mobile Hydraulics and Field Fault Diagnosis: On agricultural machinery, a compact SensoControl device is used to record short-term pressure peaks and return line contaminations during field work. With a robust adapter on the PTO shaft, the device also records the rotational speed to establish a correlation between speed, pressure, and flow. The analysis shows contamination in the pressure filter and a decreasing volume flow at high speeds, leading to the planning of a filter change and a service interval.

Accessories, Calibration, and Maintenance

Accessories include calibratable reference modules, replacement seals (NBR, FKM, PTFE), various adapter sets, pressure-stable measuring lines, and protective transport cases with individually customizable inserts. For testing and certification processes, traceable calibrations are available that document compliance with measurement uncertainties. Maintenance recommendations include regular visual inspection of seals, functional testing of sensors against a reference, and cleaning of connections. Defective electrical components can be replaced modularly; for critical applications, service contracts with factory inspection are offered. Further technical information can be found under Technik and specific practical applications under Anwendungsbeispiele.

Selection Criteria for Purchase

When selecting a suitable SensoControl handheld measuring device, the measuring range, accuracy, connection standard, protection class, and data interface are the decisive criteria. Additionally, material compatibility of the adapters and seals with the hydraulic fluid used should be checked. Pay attention to the required sampling rate for dynamic measurements and the possibility of simultaneous multi-channel measurement if pressure, temperature, and speed need to be analyzed in parallel. For recurring testing tasks, kits with specially pre-configured measuring lines and a calibration certificate are worthwhile.

Compatibility with Test and Automation Systems

SensoControl devices can be integrated into existing test benches and can communicate with controllers via standardized protocols. Optional CAN or EtherCAT interfaces enable integration into real-time controls, while USB and Bluetooth ensure easy documentation and post-processing. Open data formats allow further processing in measurement data software or ERP systems, so that measurement protocols can be automatically archived and service reports generated.

Standards and Safety Aspects

The measuring devices comply with common industry standards for electrical safety, EMC, and pressure equipment safety. When taking measurements on pressure systems, operating instructions and compliance with relevant safety regulations (e.g., DGUV, EN standards) must be observed. Personnel should wear appropriate protective clothing and install measuring adapters only when the system is depressurized or after approval, unless a quick coupling with disconnect protection is used.
