J r u control manufactures model jedpt series electronic differential pressure transmitters for measuring flow, liquid level and differential pressure. The differential pressure is converted to proportional electronic 4-20 ma output signal can be connected to dcs system/ indicating/ recording/ controlling devices. The electronic differential pressure transmitters come with working principle as one end of the primary beam is connected to double sealed diaphragm through diaphragm link. This feature isolates high-pressure chamber from low-pressure chamber and give movement to the centre of the diaphragm assembly that is proportional to differential pressure. The primary beam is fitted with sealing diaphragm at the pivot point for preventing leakage from the pressure chamber. The primary beam is linked to an rvdt so that the shaft of rvdt gets an angular movement proportional to linear movement of the primary beam. The jedpt series electronic differential pressure transmitters are available with technical specifications such as silicon oil filled double sealed ss diaphragm sensing element; cs/ ss body; 24 to 40 v dc supply voltage; 4-20 ma output; ±0.5% accuracy; 40 kg/ cm² pressure; damping built into sealed diaphragm measuring element; 4 w power consumption and 10°c to 120°c temperature
