Type 8311 Pressure Transmitter can switch valves, pumps, and relays on and off. Applications include control of air or fluid pressure in tanks, flow pressure monitoring in water treatment systems, level control in tanks, pressure monitoring in autoclaves, and pump protection systems. It measures line pressures up to 725 psi in fluid temperatures up to 212Â° F. Outputs include 4-20mA, NPN/PNP transistor, and optional 3A/230 VAC or 3A/30 VDC relays.
Lasts a Lifetime
ST2000 Lifetime pressure transmitters have a field MTBF of 470 years and come with a 15-year warranty. Accuracy is 0.0375% and stability is 0.01% per year, both for the life of the transmitter. Rangeability is 400:1 turndown, reducing inventory costs.
Honeywell Process Solutions
The P855 differential pressure transducer has an on-board microprocessor that provides 0.1% FS accuracy. It has an on-board temperature sensor and an error correction system to minimize output errors in extreme environments. It is available in full-scale pressure ranges from 2.5 in./H2O. Standard output signals are Â±5 Vdc, 4-20 mA and Â±10 VDC. RS485 is optional.
