PREC300 Pressure Transmitter

With a metallic measuring cell, the PREC 300 pressure transmitters are designed for measuring the relative pressure of liquids. This model is based on capacitive technology. The pressure acts on the isolation membrane, causing the filling liquid to deform the central membrane, which then changes its capacitance. This capacitance signal is converted to a current signal or HART. The process connection is achieved through a standard ANSI flange by default. Measurement ranges: 0-60 mbars to 200 bars Measuring scale: 40:1 (digital electronic) Accuracy: ± 0.075%, ± 0.1%, ± 0.25%, ± 0.5% Stability: ± 0.1% / year Operating temperature: -25 to 85°C by default, high temperature optional Power supply: 12 to 45 VDC (24 VDC is recommended) Output signal: 4-20 mA / HART Output load: 50 Ω Insulation resistance: >100 MΩ/50 V
