MTN/2285IW Series
Intrinsically safe submersible velocity transducer 4‐20mA output for PLC interface
ATEX & IECEx Group II approved
ATEX and IECEx Group II certified. Submersible, general purpose, top‐entry velocity transducer with DC
output. Made from robust stainless steel throughout for continuous vibration monitoring in harsh underwater
environments and areas with constant moisture or condensation. Internal electronics are enclosed in a
Faraday cage and isolated to minimise noise. Sealed to IP68 with industry standard two‐wire 4‐20mA output
proportional to sensor range that can connect directly to PLC, DCS and other industrial controllers. Includes
integral heavy duty polyurethane cable and is available with a wide range of mountings.
