Modbus infrared thermocouple
-20 - 500°C, 8 - 14 μm, RS485 Modbus | PyroBus
Calex Electronics
The PyroBus Series is a range of high quality, low cost, compact sensors which measure the temperature of inaccessible or moving objects and materials. They measure temperatures from -20°C to 500°C, accurately and consistently, with an outstanding response time of 240 ms.
Two-way digital communications via a built-in RS485 Modbus RTU interface enables the user to adjust the emissivity setting; compensate for reflected energy; apply filtering; select maximum, minimum, average or instantaneous readings; and peak or valley hold processing. Up to thirty two sensors can be installed on a single multidrop network.
All PyroBus sensors are fitted with precision Germanium lenses for accurate optics. Model PB21 has 2:1 optics making it suitable for most applications where the sensor can be mounted close to the target. Model PB151 is designed for small or distant targets and has an optical resolution of 15:1. Model PB301 is designed for very small or distant targets and has an optical resolution of 30:1.
The PM240 is a 320x240 pixel touch-screen terminal with a 3.5"colour TFT display. It allows the user to display data from up to eight PyroBus sensors and configure each sensor individually. The configuration parameters include emissivity setting, signal averaging, peak or valley hold processing and reflected energy compensation.
There are two versions available. Each one provides all of the features above, however, the enhanced PM240E also provides analogue transmission for up to four sensors, plus two adjustable alarm outputs per sensor for all eight sensors.
