TXA-33500 | METRIX TRENDSETTER

TXA series of transmitters consists of two systems, the TXR, Radial VibrationTransmitter System and the TXA, Thrust Transmitter System. Both systems contain three parts – a proximity probe, a matched extension cable and a transmitter. Both systems provide a 4 to 20 mA current loop output signal. The TXA Axial Thrust Transmitter System measures the distance between the target and the probe tip. The following equation represents the relationship between the target’s relative position and the loop current.The minimum loop power supply voltage required is 25.1 VDC plus 1 volt for each 50 ohms of loop resistance. The maximum loop power supply voltage that may be applied to the safety barrier is 26 VDC. Therefore, the maximum loop resistance with a 26VDC supply is 45 ohms.Example: Single wire resistance = 5 ohmsResistance of receiver = 50 ohmsTotal loop resistance = 55 ohmsMinimum supply voltage = 55 (1V/50 ohms) + 25.1 V = 26.2 VDC
