Description
Introduction
What temperature do you need to reliably read from a surface and make available to your building management system? The Thermokon OF14+ temperature Sensor Modbus is a cable probe for surface temperature measurement with RS485 Modbus communication. The Sensor combines a compact aluminum Sensor sleeve with a robust USE-M housing. In addition, the device supports various configuration options, making it practical for use in control engineering installations.
Key features
- Measures temperature on a surface with an aluminum Sensor sleeve.
- Provides data via Modbus over an RS485 Interface.
- Has protection rating IP65.
- Operates within a temperature range of -35 to +70 °C.
- Has a 1 meter connecting cable and a self-adhesive Sensor surface for surface mounting.
- Supports configuration via USEapp, uConfig, BUS, jumpers and DIP switches.
- Comes with mounting base, mounting set, screws and accessories.
Applications
This Thermokon OF14+ temperature Sensor Modbus is suitable for situations in which the temperature of a surface must be made centrally available. Think of installations in which a surface Sensor forms part of an HVAC control or building management system. The cable probe can be used on a surface that you want to monitor locally and whose measured value must be read out via Modbus.
The included mounting set supports practical installation. In addition, the 1 meter cable makes the Sensor usable when the housing is placed some distance from the measuring point. For other measurement solutions, you can also view the category surface sensors.
