Allen-Bradley 837T solid-state temperature sensors offer a high-accuracy comprehensive solution for measuring temperatures in liquids, gases and vapours. The 837T display model has temperature measurement ranges from -20°C to 80°C and features IO-Link communications protocol. IO-Link allows sensors to easily integrate with the connected enterprise, delivering data from the sensor directly into a control system in an easy-to-use manner. Easy on-machine programming allows the sensors to be configured manually through the Studio 5000 Logix Designer software.

Temperature Range: -20…80 °C

Achieve accurate temperature measurements in liquids, gases and vapours with this Pt1000 RTD sensor from Rockwell Automation's Allen Bradley range. Its head rotates by 330° and results are shown in red characters on an integrated digital display, so readings are easy to capture. A built-in IO-Link lets you make connections for the delivery of data from the device to a control system. You can also configure the component for on-machine programming. An IP67 rating assures you it's completely dust-tight and protected from submersion in up to one metre of liquid, so you can rely on it for safe use in tough environments. You'll find sensors like this in electronic devices, automotive systems and telecommunications equipment.

• 320° rotatable housing for easy handling

• 100mm probe to easily reach into tight spaces

• EN 60751
• RoHS
• UKCA-conformity

No, an RTD sensor isn't sensitive to polarity. It uses a resistor to measure electrical current in ohms and then converts it to a temperature reading.
