The seawater temperature sensor OMC-448 provides an accurate measurement of temperature, using a Pt100 sensing element. A build-in amplifier is provided with a 4…20 mA output. This corresponds with –40 to +60 deg. C. Of course other ranges are available on request. The OMC-448 has a 1/2” NPT connection and fits in the OMC-449 (water temperature). The OMC-449 Thermowell is made of stainless steel 316 and has a 1/2” NPT connection and can be mounted in sea water inlet.
