MTN/2285STC: a combined velocity and temperature sensor

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 per cent.

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/degC across its operating temperature range of -25 to 90degC, and it has an accuracy of 0.08 per cent/degC.

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."
