167 Low Differential Pressure Transducer
2Pages

Low Differential Pressure Transducer alpha" instruments The Model 167 Series 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 Model 167 Series are available for full scale pressure range from 0 to 0.1"WC till 0 to 100"WC. Both unidirectional and bidirectional pressure ranges are offered. The output of the Model 167 Pressure Transducer is available in two versions: 0 to 5VDC and 0 to 10VDC, where 0VDC is true zero without offset. The output of Model 167 Pressure Transmitter is 4 to 20 mA. The Units can be temperature compensated to 0.01%FS/°F. The accuracy can be 0.6%, 0.4% or 0.25% at room temperature. The patented variable capacitance pressure sensor is constructed by stainless steel and glass, no glue or other organics. That provides excellent performance, corrosion resistance and long-term stability. Additionally, our unique production setup allows us to accommodate special orders for nonstandard pressure ranges (e.g. -0.5"WC to +3.5"WC).
