Series 251 - Wet/Wet Differential Pressure Transmitter

Wet/Wet Differential Pressure Transmitter

The Series 251 wet/wet differential pressure transmitter utilizes a double diaphragm sensor technology that outperforms standard double sensor products in accuracy, reliability and static operating pressure. This differential pressure sensing technology offers 0.25% accuracy with static operating pressures up to 1000 PSI. The Series 251 features 316 stainless steel construction designed to meet NEMA 4X (IP 65) standards. The transmitter also offers exceptional field flexibility with a 5:1 turn down and comes standard with a certificate of calibration.
