Frequently Asked Questions
Application Questions
What machines need this high-temperature sensor?
Use it on equipment near engines, ovens, steam systems, or hot processes. It is ideal for areas where standard sensors would fail from heat.
Can I connect this directly to my PLC?
Yes, if your PLC has a 4-20 mA input card. The two-wire design connects directly. No extra signal conditioner is needed.
Installation & Tips
How tight should I screw in the transducer?
Use a wrench to tighten firmly. Do not over-tighten. The metal mounting base should sit flush against the machine surface for a good reading.
My reading is stuck at 4 mA. What does this mean?
A 4 mA output usually means zero vibration. First, check if the machine is running. If it is running, there may be a wiring problem or the sensor is damaged.
Buying Guidance
I need a sensor for a very hot pump. Is the 74712-03-10-02-00 the right choice?
Yes. The 74712-03-10-02-00 is specifically designed for high-temperature pumps and similar applications. Just verify your mounting hole is M10 x 1 threaded.
