DETAILED DESCRIPTION

PB151
The PyroBus series is a range of compact IR sensors measuring temperatures from -20°C to 500°C with a response time of 240ms.
Two-way digital communication via a built-in RS485 Modbus RTU  interface enables the user to adjust the emissivity setting, compensate for reflected energy, apply filtering, select maximun/minimum/average or instantaneous readings and peak or valley hold processing.
The PyroBus may be installed as a standalone network of sensors, or integrated into an existing Modbus network.
There are applications for the PyroBus in a wide range of industries including food processing, plastics thermoforming, automotive, power industry, gas cylinder filling.
