CMCP-3070A Intrinsically Safe Magnetic Speed Sensor

This sensor is specifically engineered for use in gas, oil and petrochemical industry applications. It is an explosion-proof design and UL approved for Class I - Group A,B,C,D hazardous locations. Class II - Group E,F and G.

 

CMCP-3070A additionally offers other advantages such as a wide air gap range as well as low impedance which makes it particularly well suited for transistor circuit inputs. The stainless steel shell is completely sealed and when mated with conduit provides protection against damage due to water, oil, dirt, dust, humidity or corrosive liquids.

 

Installation:

When used in hazardous locations, appropriate conduit fittings must be used as defined in Articles 500, 501, 502 and 503 of the National Electrical Code. Models are provided with 1/2” international pipe threads to accommodate the conduit fittings and with #18 AWG stranded leads for splicing in conduit boxes suitable for the application.

 

Adjustment:

Make sure there is sufficient clearance between the pickup and the actuating medium (exciter gear) to prevent damage to the pickup. The recommended procedure is as follows:

With the pickup part of the actuator at rest in front of the pickup, advance the pickup until it just touches the actuator and then back off the pickup by a known amount. The 3/4”-20 thread advances 0.0500” per turn.
