Interface and Signal Connection Details
This unit connects through a two-wire loop output cable. Therefore, technicians achieve simple wiring inside crowded junction boxes. The transmitter converts probe signals into a standardized current output. In addition, it draws 24 V DC directly from the loop supply.
Physical Characteristics and Mounting
The device measures roughly 100 mm wide and 75 mm high. Furthermore, its 60 mm depth suits compact machine-side enclosures. It weighs about 0.6 kg. Consequently, it adds minimal load to bracket assemblies. Installation uses a bracket or panel mount, then technicians tighten the retaining hardware.
Operational Role and Maintenance
Engineers apply this transmitter for axial displacement monitoring and thrust bearing protection tasks. Meanwhile, front-panel indicators show live signal status during troubleshooting. The unit holds no battery or capacitor for energy storage. Thus, it avoids periodic cell replacement work. Instead, it relies entirely on the loop supply for power.
