DESCRIPTION

Model 168 Series are low range differential pressure transducers and transmitters with NEMA 4 (IP-65) rated aluminum enclosures. They are very rugged and reliable, good for many industrial applications. The pressure range covers from 0.1"WC to 100"WC, unidirectional or bi-directional. The output can be 3-wire 0-5V, 0-10V or 2-wire with a 4-20 mA output, fully protected against short circuits and incorrect wiring. In the voltage version, the output can go down to true zero. The units can be temperature-compensated. The accuracy can be 0.8%, 0.4% or 0.25% at room temperature. The patented stainless steel sensor provides good corrosion resistance, excellent performance and long-term stability. Our unique production setup can also make special pressure ranges (e.g. -0.5"WC to +3.5"WC) to meet special applications.
