Pressure transmitter (data sheet 9860.2)

Pressure transmitters DIGPTMv are designed for measuring and monitoring absolute pressures and overpressures of liquid and gaseous media for measuring spans from 4 bar up to 160 bar. By integrating a separate temperature sensor and linking the pressure and temperature signal in the internal microprocessor, a higher stability and accuracy is achieved over the entire rated temperature range.
The robust all-metal version and the resulting EMC stability (double test level) make the DIGPTMv ideal for industrial applications. The use of stainless steel guarantees a high degree of protection and high chemical resistance.
With its two switching outputs, freely programmable regarding switching function, switching point and switching hysteresis, and with the integrated RS-485 port, the DIGPTMv is a synergy of pressure transmitter and pressure switch combined in one instrument. Simple, pressure-controlled switching operations can be realised without any additional SPC or logic modules and managed by the user at any time with the software via RS-485.
