Alpha instruments is an experienced differential pressure transmitter supplier and 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 transmitter and intrinsically safe pressure transducer are low range differential pressure transducers and hvac differential pressure transmitter with 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 sensor provides 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.
