The CAPM-2 Carrier Frequency Sensor is used with JV-CG and JV-KG meters (NOT FOR USE WITH ALUMINUM METERS). Carrier Frequency means there is no permanent magnet in the pickup, and any magnetic drag on the flow meter is avoided. The CAPM-2 requires a supply voltage between 10 VDC and 30 VDC. A diode in the supply input prevents damage to the module in case the polarity of the supply voltage is wrong. The output signal is a square wave, voltage pulse of approximate amplitude (supply – 1.5 V).
*CAPM-2N is used with the HPM series and the TR series of flow meters
*CAPM-2o is a UL & cUL approved, intrinsically safe pickup sensor for use in Class 1, Div. 1 locations
Features include:
Sourcing output (PNP type sourcing open collector transistor)
Intrinsically safe CAPM-2o version available
IS safe version UL & cUL certified for use in Class 1, Div 1 locations
Output signal is a square wave, voltage pulse of approximate aplitude (supply - 1.5V)- the frequency is proportional to the flow rate
