VCM-EE in Explosion-Proof Enclosure
MPS’ most popular model in a protected explosion-proof enclosure. Applicable for Explosion-Proof Environments.
For the most complete protection on large, or critical machines, the VCM-E is ideal due to its higher shaft current measurement capacity, uninterrupted grounding, continuous monitoring via 4-20mA signals and alarms for alerting operators to dangerous conditions such as brush performance failure or increase in shaft voltage. VCM-E’s continuously monitor shaft voltage and/or grounding/earthing current providing three 4‑20 mA output signals (per VCM-E) for remote monitoring and trending.
- Explosion Proof
- Prevent Shaft Current Damage
- Shaft Current Sparking Confined or Controlled
- Train Performance Tracking, Aiding Operation
- Continuous Train Performance Sensing and Tracking
- Continuous Train Trending Aiding in Maintenance Scheduling
-
- Alarms when shaft grounding devices have lost contact with the shaft.
- Alarms on high and low grounding current and/or high shaft voltage.
