Combined Velocity & Temperature Sensor with 4-20mA Range Outputs Launched

Monitran, an industry leader in the development and manufacture of sensors and condition monitoring systems has launched the MTN/2285STC. It is a dual-output sensor ideal for monitoring vibration and temperature levels in the same location and for protecting motors, fans, pumps, compressors and other assemblies with rotating parts.

Both of the sensor’s outputs are in the industry-standard range 4-20mA and are suitable for direct connection to a Programmable Logic Controller (PLC), Distributed Control System (DCS) or other industrial controller.
Andy Anthony, Managing Director of Monitran, comments: “Changes in vibration or temperature levels tend to provide the earliest indication that a piece of plant or equipment is in need of maintenance, and in some cases warrants shutting down to avoid damage. With our new dual-output sensor, engineers can connect directly to any equipment that accepts inputs in the 4-20mA range in order to monitor both parameters for maintenance, control or emergency-shutdown purposes.”
The MTN/2285STC is a stainless steel side-entry transducer, sealed to IP65 and supplied with 5m of integral stainless steel over-braded ETFE cable as standard with other lengths available upon request. Its dynamic range is 50g peak and it has a frequency range of 16Hz to 720Hz ±10%.
The sensor requires a DC supply voltage in the range 12 to 32V. Its Vibration output is proportional to RMS velocity with a range of 0 to 10, 20, 25, 50 or 100mm/S; to be specified when ordering. The sensor’s Temperature output sensitivity is 0.106mA/oC across its operating temperature range of -25 to 90oC, and it has an accuracy of 0.08%/oC.
Anthony adds: “Most velocity sensors that also measure temperature usually do so because of the addition of an AC output – i.e. they produce a voltage proportional to acceleration or velocity. It is therefore often necessary to convert the voltage into a current, in the range 4-20mA, in order to connect to monitoring or control equipment. With the introduction of our new sensor we are negating the need for the conversion step.”
