Model 167 DIN Rail Mount 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 167 series negative pressure sensors are low range differential pressure transducers and transmitters. It was specially designed for 35mm DIN Rail Mount, which dramatically reduces the required mounting space and installation cost. The green and red LED indicators show the working status of the unit in the field.
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 negative pressure transducerprovides 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.
