Technical Explanation for ESI Pressure Sensors Technical Explanation What is a pressure transmitter? In the silicone-on-sapphire technology, the substrate of the thin film measuring cell is synthetic sapphire. This has excellent mechanical and temperature stable properties and prevents undesired parasitic effects, thereby having a positive effect on accuracy and stability. In conjunction with a titanium membrane, this results in virtually unique coaction between the temperature coefficients of sapphire and titanium. This is because, unlike silicon and high-grade steel, they are more closely...

Standard signals Output signals 4 - 20 mA, 0 - 5 V and 0- 10 V in particular are established in the industry. Unamplified millivolt (mV) output signals are available for some variants. Also offered are transmitters with digital USB output or customer-specific output signals (such as 1 - 5 V). Output configuration The output configuration for a 4-20 mA signal is a 2 wire connection. For 0-5 V and 0-10 V signals, the configuration is either 3 wire or 4 wire connection depending on the model variant. All mV outputs are 4 wire. transmitter, the supply voltage should not fall below the minimum...
