RFID pressure transmitters for hydraulic applications

as a standard, including media temperature, date and time of the measurement, and the unique serial number of the pressure transmitter. The software included with the unit allows subsequent evaluation and further processing of the measurement results previously transmitted to the PC or notebook via the USB interface. The pressure transmitters are available in five different versions and cover the usual measuring ranges for hydraulics between 0-16 bar and 0-600 bar (absolute), depending on requirements, with a precision of max ±1 per cent full scale. Temperature values can be displayed from -40°C to +85°C. The pressure transmitters are available with ¼" BSPP (with FPM profile sealing rings) or ¼" NPT screw- in threads. Corresponding connection pieces are available for the temporary or permanent use of existing test couplings. Measurements can be carried out at the press of a button, without extensive training and within a few seconds, and then documented in a reliable process.

STAUFF presented its PT-RF series of pressure transmitters at Hannover Messe 2015. The innovation in the field of universal pressure measurements for fluid technology applications will provide benefits for system operators, maintenance personnel and repair technicians, as well as for original equipment manufacturers. The use of these transmitters in a hydraulic system allows the wireless collection of pressure data without having to connect measuring devices to the user’s equipment, eliminating the possibility of introducing contamination into the system and speeding up the process. The operating principle of the pressure transmitters is based on RFID (radio frequency identification) technology. The energy required for a measurement is transferred to the pressure transmitter via the antenna of the associated reading and display device so that the transmitter requires no internal or external power supply in the traditional sense (eg in the form of a battery) and no external wiring. As well as the system temperature, other relevant information is transmitted

devices – practically a temporary opening of the system – is not required. Potential hazards for people, machines and the environment, for example from emitted residual oil in the test hose or leaks at the measuring point, as well as ingress of dirt into the system (eg in dusty environments) can be effectively excluded.
