Geotech Pressure Transducers
Geotech's submersible pressure transducers are designed for ruggedness and long life to meet the demanding environments encountered in liquid level measurement and control.
- High static accuracy and repeatability
- 100% computer tested and calibrated
- Temperature compensated measurement
- Signal outputs of 4-20 mA, 1-5 Volt output, and Modbus RS485
- User specified pressure ranges from...
– 100-1500 psi (7-100 bar) Sealed Gauge
– 15-1500 psi (1-100 bar) Absolute - All wetted materials are #316 stainless steel
- Designed to be intrinsically safe
- Cable is premium quality, double-shielded, yellow polyurethane jacketed Tefzel®,
or blue modified PVC blend - Sensor has ¼" NPT process fitting with protective cap
- Optional surge suppressor for lightning protection
