140T- Hazardous

Intrinsically Safe Vibration Transmitter

The Model 140T intrinsically safe vibration transmitter is low cost, yet highly accurate and rugged. It is ideal for use with all machines, even those which previously may have been considered uneconomical to monitor. The Model 140T easily mounts by use of a standard 1/4"-20 stud. It is a two-wire, loop-powered transmitter which can feed the vibration level of operating machinery to a data logger, milliamp monitor, or process control computer. Solid state accelerometer and circuit design provide a 4-20 mA signal proportional to vibration velocity. Intrinsically safe, it can be used in hazardous environments when coupled with a Model MTL7706 Intrinsic Safety barrier.
