LPG 400 LPG 400 Pneumatic Pressure Controller. This modular instrument (up to 2 sensors) offers maximum flexibility in terms of configuration to customer requirements. The instrument stands out due to its pressure sensors, which are based on MEMS technology, and which are combined with the highest precision and the highest long-term stability. The LPG 400 achieves stability control of 0.005% FS of the currently active pressure range. The equipment operates intuitively via a touch screen. All extended functions are accessible through submenus. In addition to the optional calibration software, which allows comfortable calibration of instruments, including the automatic creation of pressure measurement test certificates, the user is able to create own software programs. For integration into existing systems there is an RS-232, USB, LAN port. Also, transmitter calibration and CSV-exportable logging function via USB are available. They allow the use of liquids (not viscous) in their operation. On request, stationary or completely mobile test equipment can be manufactured.
