Bestech Australia offer the model 5000 wet/wet differential pressure sensor from American Sensor Technologies.
The 5000 model pressure transducer/wet differential pressure sensor offers measurement of both liquids and gases compatible with stainless steel, without the use of fluid-filled cavities. This eliminates the risk of system contamination and at the same time offers benefits associated with AST’s MEMs-based Krystal Bond technology.
In the event that one pressure port is at full line pressure and the other at zero, no damage can be done to this pressure transducer/transmitter.
Applications for the 5000 model wet differential pressure sensor include filtration, hydraulic systems, gas compressors and water management.
Measurements are available in differential pressures covering line pressures up to 1000PSI. Burst pressure is the lesser of five times the rated line pressure and 2000PSI.
The accuracy (consisting of non-linearity, hysteresis and non-repeatability) of the differential pressure sensor is ±0.3%. There is a total error band of ±1.5% of full scale, and the unit can survive high pressure cycles. Available electrical outputs include 4-20mA, various voltage outputs and 0.5-4.5V ratiometric.The 5000 model wet differential pressure sensor/pressure transducer is compact and rugged in design, with high strength stainless steel construction. It has an operating temperature of -40° to 85°C, and has a protection rating of IP66. The 5000 model wet differential pressure sensor can also survive large shocks and vibrations.
