Model 168 intrinsically safe Differential Pressure Transducer

• 

Alpha instrumentsis an experienced differential pressure transmitter supplierand differential pressure transducer manufacturer/factory. We are very proud to provide pressure transducers and transmitters for HVAC and other fields. We have low to mid-range pressure sensors available. With our unique product design and production set-up, we strive to meet any customer’s needs.

Model 168 series intrinsically safe pressure transmitterand intrinsically safe pressure transducerare low range differential pressure transducers and hvac differential pressure transmitterwith NEMA 4 (IP-65) rated aluminum enclosures. They are very rugged and very reliable, good for many industrial applications.

The pressure range covers from 0.1″WC to 100″WC, unidirectional or bidirectional. The output can be 3-wire 0 to 5V, 0 to 10V, or 2-wire 4 to 20 mA, fully protected against short circuit and incorrect wiring. In the voltage version, the output can go down to true zero. The units are temperature compensated. The accuracy can be 0.6%, 0.4% or 0.25% at room temperature.

The patented stainless steel intrinsically safe pressure sensorprovides good corrosion resistance, excellent performance and long term stability.

Our unique production setup can also make special pressure range (e.g. -0.5″WC to +3.5″WC) to meet special applications.
