摘要：
An intrinsically safe serviceable transmitter apparatus and method includes a sensor module composed of at least a sensor and a sensor electronic module in order to transmit an electrical signal from the sensor module to a dual cap electronic housing module. The dual cap electronic housing module includes an electronics module, a terminal block, and an intrinsically safe circuit and noise rejection unit. The electronic housing module includes a meter cap and a field-wiring cap in order to permit a user to open either side of the transmitter housing in an intrinsically sale environment. Once open, a local integral meter can be added to calibrate and reconfigure the apparatus and/or to replace a communications board. The terminal block located in a field-wiring compartment acts as an intrinsically safe barrier for the rest of the transmitter electronics and simplifies board replacement.
