Abstract:
1. An intrinsically safe transmitter apparatus, comprising: a sensor module having a sensor and a sensor electronic module wherein said electronic sensor module comprises a process variable and advanced diagnostics unit, a primary programmable gain amplifier and analog to digital converter, and a secondary programmable gain amplifier and analog to digital converter; an electronic housing module having an electronic module, a terminal block and an intrinsically safe circuit and a noise rejection unit, wherein said electronic housing module receives an electrical signal from said sensor module; a meter cap and a field wiring cap located on said electronic housing module, which permits a user to open either side of said electronic housing module in an intrinsically safe environment; and a local integral meter connected to said electronic housing module in order to calibrate or configure said transmitter apparatus wherein said terminal block located in a field-wiring compartment acts as an intrinsically safe barrier for said transmitter apparatus and simplify said board replacement.
