1 General Specifications Model EJB430 Gauge Pressure Transmitter GS 01C23E01-00E [Style: S2] The model EJB430 Gauge Pressure Transmitter can be used to measure liquid, gas, or steam pressure. It outputs a 4 to 20 m DC signal corresponding to the measured gauge pressure. The model EJB430 also features remote setup and monitoring through communications with the model BT200/100 BRIN TERMINL, CENTUM CS/XL system etc. STNDRD SPECIFICTIONS Measurement s: Capsule B Measurement Span 0.06 to 3 MPa {0.6 to 30 kgf/cm 2 } Measurement -0.1 to 3 MPa {-1 to 30 kgf/cm 2 } 0.46 to 14 MPa -0.1 to 14 MPa {4.6 to 140 kgf/cm 2 } {-1 to 140 kgf/cm 2 } Maimum Overpressure 4.5 MPa {45 kgf/cm 2 } 21 MPa {210 kgf/cm 2 } T01E.EPS Output Signal: 4 to 20 m DC, 2-wire system with digital communication Failure larm: Output status at CPU failure and hardware error; Up-scale: 110%, 21.6 m DC or more (standard) Down-scale: -5%, 3.2 m DC Conditions of Communication Line: Power supply voltage; 16.4 to 42 V DC Load resistance; See Figure 1.

The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm and the fill fluid can contaminate the user's process fluids. Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150 ºC [302 ºF] or above).
