Product Description DPT281 600bar air pressure transmitter with digital indicator Profiles: DPT281 pressure transducer/transmitters use high quality imported piezoresistive pressure sensor with isolated stainless steel diaphragm as signal sensing element, through automatic testing, laser trimming compensating zero and sensitivity in wider temperature range the amplifier circuit is in stainless steel housing, transforming sensor signal into standard output signal. Through strict component making, semi-finished product and allfinished product testing and aging, the transmitter is stable and reliable, having excellent flexibility, sensitivity and diversity. The product is widely used for pressure measure and control of petroleum, chemi-industry, metallurgy, power station and hydrology, etc.
Characters: - Accuracy: ≤±0.5%F.S.
- Wide working temperature scope
- Advanced digital temperature compensation.
- Excellent resistance against impact, overload,
Shock and erosion. - Highly-efficient lighting absorption
and strong RFI & EMI resistance - 4-1/2 bits LED display for pressure or level
