PyroBus NonContact Temperature Sensor with RS485 Modbus Interface An innovative range of compact infrared pyrometers with builtin digital communications for easy systems integration
Wide temperature range from 2 C to 5 C Builtin RS485 Modbus RTU Interface Configurable emissivity setting and signal processing Max; min; average and instantaneous readings; peak or valley hold; reflected energy compensation 2:1, 15:, 3:1 or close focus optics Fast response with high stability Stainless steel housing, sealed to IP65 Quick and easy installation Optional air/water cooled housing, air purge collar, laser sighting tool and mounting brackets Optional PM24 TouchScreen Terminal for configuring and displaying data from up to eight PyroBus sensors 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 2 C to 5 C, accurately and consistently, with an outstanding response time of 24 ms. Twoway digital communications via a builtin 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 PB31 is designed for very small or distant targets and has an optical resolution of 3:1. Model PBCF is designed for targets as small as ø5mm at a distance of 1mm from the sensor. These compact sensors are small enough to fit almost anywhere and their rugged stainless steel housings make them ideal for applications where cleanliness and hygiene are paramount.

All PyroBus Series Sensors are supplied with a stainless steel mounting nut and are easy to install. Standard sensors will operate in ambient temperatures up to 7 C. For more hostile environments or difficult mounting conditions a wide range of accessories is available. Accessories Fixed mounting bracket The Lshaped fixed mounting bracket offers a rigid support for the sensor and allows fine adjustment in a single plane. Adjustable mounting bracket The adjustable mounting bracket consists of a fixed mounting bracket plus another Lshaped bracket. When assembled as shown the adjustable mounting bracket offers a rigid support for the sensor and allows fine adjustment in two planes. Air purge collar The air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front. Air/water cooled housing The air/water cooled housing allows the sensor to withstand ambient temperatures which exceed the normal 7 C limit. Air or water (depending on the degree of cooling required) flows into one of the fittings on the side and out of the other. To prevent condensation forming on the lens, the air/water cooled housing is supplied complete with an air purge collar. Please note, the air/water cooled housing must be ordered with the sensor and cannot be fitted by the user. Laser Sighting Tool The Laser Sighting Tool screws onto the front of the sensor during installation and indicates precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position the Laser Sighting Tool can be removed. The laser is activated by means of a push button on the front of the tool which has a latching mechanism.

It is made of stainless steel, sealed to IP65, and will operate in ambient temperatures up to 7 C without additional cooling. This makes the PyroCouple M Series ideal for applications where there is only a small amount of room available to mount the sensor or the ambient temperature around the sensing head is higher than normal. The electronics module measures 98mm x 64mm x 34mm. It is made of diecast aluminium, sealed to IP65, and will operate in ambient temperatures up to 7 C. It is powered from a 24 VDC (28 VDC max) power source. The emissivity setting is fixed at.95, making the PyroCouple M Series suitable for the majority of applications where the target is made of a nonreflective material such as paper, plastic, rubber, cloth, food etc. or it can be used to measure metals that are painted, anodised or oxidised.

This second output can be used to ensure that the sensor is being operated within the correct ambient temperature limits and prevent damage caused by overheating or overcooling. It can also be used to give an approximate indication of the air temperature surrounding the sensor.

Model PC21 has 2:1 optics making it suitable for most applications where the sensor can be mounted close to the target. Model PC151 is designed for small or distant targets and has an optical resolution of 15:1. Model PC31 is designed for very small or distant targets and has an optical resolution of 3:1. Model PCCF is designed for targets as small as ø5mm at a distance of 1mm from the sensor. Accessories Fixed mounting bracket The Lshaped fixed mounting bracket offers a rigid support for the sensor and allows fine adjustment in a single plane. Adjustable mounting bracket The adjustable mounting bracket consists of a fixed mounting bracket plus another Lshaped bracket. When assembled as shown the adjustable mounting bracket offers a rigid support for the sensor and allows fine adjustment in two planes. Air purge collar The air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front. Air/water cooled housing The air/water cooled housing allows the sensor to withstand ambient temperatures which exceed the normal 7 C limit. Air or water (depending on the degree of cooling required) flows into one of the fittings on the side and out of the other. To prevent condensation forming on the lens, the air/water cooled housing is supplied complete with an air purge collar. Please note, the air/water cooled housing must be ordered with the sensor and cannot be fitted by the user. Laser Sighting Tool The Laser Sighting Tool screws onto the front of the sensor during installation and indicates precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position the Laser Sighting Tool can be removed. The laser is activated by means of a push button on the front of the tool which has a latching mechanism. Issue C July 1 Specifications subject to change without notice
