Digital transmitter to be built into own equipment

OEM202W is a digital temperature transmitter for integration into temperature sensors, systems or machines, for converting a low-signal level output to an amplified signal. OEM202W is compatible with both Pt100 and Pt1000, as well as 2-, 3- and 4-wire connections. The great connectivity options combined with the compact design makes it suitable for most types of applications and sensors.

The transmitter is connected to the process and sensor with solder pads.

Proven in use
OEM202W is based on INOR’s latest transmitter platform which makes it very accurate and reliable. Just like the other transmitters in the new platform, it offers numerous smart features to give you a better control of your process.

Customizable to your needs
Already in the standard configuration, OEM202W offers high performance and many functions. Should that not be enough we can make adjustments both physically and technically to meet your specific needs. Examples of such adjustments are adjusting the form factor to fit your particular application or enabling measurement with both PTC, NTC and PtX elements.

Smart features for more reliable measurement
What stands out with OEM202W is its reliability. Smart functions such as sensor error correction and system error correction help you to automatically correct for known sensor and system errors.
