Dynamic Output
Both the CMCP420VT‐01 and CMCP420VT‐02 are supplied with a 100mV/g Dynamic
Output, available on the D+ and D‐ terminals. Vibration analyzers should be set to not
provide constant current power when used.
Calibration
The CMCP420VT/Ex is factory calibrated prior to shipment to meet the specifications
published in the datasheet. Calibration certificates are available upon request.
Maintenance
The CMCP420VT/Ex is non‐serviceable as all electronics are epoxy encapsulated. General
routine maintenance should be done as required to verify the sensor is firmly mounted
and all connections to the sensor are secure. The cover of the housing must remain closed
during normal operation. A set screw is provided to secure the cover to prevent
unauthorized access.

**Installation Note**
The equipment is not covered by the ATEX and IECEx certificates if the sensor is not
correctly installed in the flameproof enclosure provided with the sensor.

- Page 2 Introduction Installation Note: The CMCP420VT/Ex Series Sensors are ATEX/IECEx approved 4‐20mA output sensors designed to monitor machinery health and provide reliable real‐time data to improve Various mounting adapters, pads and adhesives are available for alternate mounting machine reliability. The series is available in two primary type, either Vibration only or techniques. Contact STI for more information. Vibration and Temperature. Both sensors provide a 4‐20mA output for each parameter though the Vibration only model also includes a buffered 100mV/g dynamic signal output on the terminal block. The CMCP420VT Series are typically installed on a bearing housing, Wiring Details or machine frame, and connect back to the user’s PLC, DCS, SCADA or other control system where the 4‐20mA signals can be recorded, trended or displayed. Each CMCP420VT/Ex sensor is provided with an approved flameproof housing.
