Webtec HPM7000: a new dawn for portable hydraulic data loggers

July 18, 2021

Webtec’s new HPM7000 hand-held hydraulic data logger meets the demands of a broad user profile, including those involved in hydraulic system diagnostics, test stands, pre-dispatch inspection or research and development. With the highly versatile HPM7000 portable hydraulic data logger, which is the successor to Webtec’s popular long-standing HPM6000 model, users can obtain quick answers to their biggest hydraulic challenges. The HPM7000 allows repair, test, inspection and R&D professionals to connect up to 48 sensors and create different hardware configurations simply by adding or changing input modules.

Among the users set to benefit are test stand technicians who want to monitor and record variables such as flow, temperature, pressure, current, rotational speed and contamination, perhaps following the repair or rebuild of pumps, motors, pistons or valves. Using the HPM7000 eliminates the complex and time-consuming process of collecting data with pen and paper, and manually transferring this information to a PC and creating a certificate.

The device will also bring advantages to R&D professionals developing/analysing hydraulic machinery such as tractors, excavators and industrial systems. With the HPM7000 it is simple to collect traditional flow, temperature and pressure readings, and seamlessly integrate new J1939 or CANOpen sensors of different type or manufacturer into a single data-logging device.

For pre-dispatch inspection (PDI) users, the HPM7000 will help improve customer satisfaction and reduce warranty claims. Using the Webtec device, PDI technicians can provide a far richer data set in support of machine/equipment performance prior to shipment, reducing the likelihood of end-user complaints.

Delivering plug and play functionality, the HPM7000 base model enables the simultaneous connection of up to 48 Webtec CAN sensors, or up to five external third-party CANopen sensors. Two frequency inputs or digital I/O are also possible thanks to a dual-function connector, thus facilitating the simple integration of gear flowmeters or speed sensors, for example.

The base model features two module slots which host the CAN input module and/or the analogue input module. With the former, users are able to connect CAN, CANopen, J1939 or any mixture of CAN protocols in a passive way (this module does not supply any power to the sensors), while the analogue input module enables back compatibility with sensors featuring SR (sensor recognition). The analogue module also enables connection to current (e.g. 0-20 mA or 4-20 mA) and/or voltage (e.g. 0-5, 0-10 V) sensors.

Despite its compact size, the Webtec HPM7000 features a 7-inch colour touchscreen display that is suitable for use with gloves, while additional large tactile buttons to the right of the screen allow operation in adverse conditions.

Users can configure the illuminated, anti-glare screen to display the readings in numerical, bar graph, dial or graphical display mode. A variety of different data-logging modes are available with the ability to record up to 16 million measured values per test at variable intervals from 1 ms, with a total possible storage size of 12GB (approximately 250 measurements).

It is possible to export all data to a PC running HPMComm 7.5 software (supplied) for further analysis or storage. HPMComm7.5 is fully compatible with Windows 10 for easy operation and accurate hydraulic analysis. By documenting the date, time and any notes with each measurement, users can quickly and cost-effectively generate certificates.

Powered by a battery or an external power supply, technicians can take advantage of a carrying strap, foldable stand or wall mounting points on the rear (for fixed installation such as test benches). The IP65-rated device features a rubberised case for protection in challenging operating environments.
