Atlas Copco Sensor 1089057554 Air Compressor Pressure Sensor

Factors to consider when choosing a pressure sensor

• Pressure range. At the very least, this should cover the maximum pressure permissible in your equipment. Excess pressure is a common cause of air pressure sensor failure.
• Precision. Most air pressure sensors are reasonably accurate at room temperature but less so at higher temperatures. If accuracy is a priority, choose a sensor with a high-precision specification and use digital electronics. Sensors offering calibrated and temperature-compensated signals are available.
• Location flexibility. Vibration, shocks and high temperatures may affect sensors placed close to the equipment they monitor. If installation at a distance isn’t possible, look for a robust design. If sensors may be exposed to hot or wet weather, ensure their housing offers suitable protection.
• Compatibility. Will the sensor’s fittings allow it to thread easily onto your existing set-up? Is its analogue output compatible with your signal conditioning instrumentation?
• Response time. Some pressure transmitters allow easy adjustment of response time, which can be useful in eliminating false triggering.
• Price. Don’t pay more than you need to, but bear in mind that with low-cost sensors you’ll have to compromise on things like durability and accuracy.
• Lifetime cost. Factors like ease of installation, low maintenance needs, robustness and longevity should be assessed alongside the purchase price.
