PCC420 series 4-20mA sensors

Vibration monitoring plays an essential role in predictive maintenance through detection of the vast majority of machinery faults. Trending vibration data allows you to monitor a variety of machines without the need for detailed spectrum analysis. The use of 4-20mA sensors establishes a cost-effective condition-based monitoring program that can be used even if you’re not a vibration expert. The overall level of vibration is represented by a loop current of 4-20 mA, where 4 mA represents no vibration and 20 mA represents a sensor’s full scale vibration level. This loop current indicates general machine health with no complex analysis required when compared against standard vibration guides. Since many process control systems already accept 4-20 mA inputs, vibration data can be incorporated with common monitoring parameters such as pressure, temperature or flow. Incorporating 4-20mA vibration transmitters increases the effectiveness of vibration monitoring programs by providing data around the clock, offering a new level of protection. The PCC420 series offers acceleration or velocity output in terms of RMS or peak, multiple full scale values, and two connector options. Metric full scale options are available for PCC420V models (10, 20, 25 or 50 mm/sec). With a velocity output, it's even easier to utilize vibration data by comparing readings against the ISO 10816-3 standard, shown above.
