Pressure transducers today are more rugged and reliable than ever before. Made of rugged
stainless steel construction, they provide abundant overpressure protection, improved total
error band (TEB) and offer negligible orientation and vibration effects. They are ideal for
long-term use in harsh environments of extreme temperature, humidity and vibration.
Still, pressure transducer installations occasionally fail. Typical problems include: improper
wiring, incorrect polarity, short circuits, inadequate power supply, multiple grounds, system
operations issues or a problem with the pressure transducer itself.
Fortunately, it’s easy for technicians to perform simple troubleshooting techniques to determine
if the transducer is operational, regardless of whether it’s a 3-wire voltage output,
4-wire voltage output, or a 4-20 mA loop transmitter. The troubleshooting procedures below
will help a technician quickly and easily determine transducer status.
