DOL 119 Sensor 5000/10000 PPM 4-20 mA

Manufacturer item no.: 140332

DOL 119/140332 is a sensor for measuring carbon dioxide/CO2. The sensor is intended for measurement in livestock houses and industrial environments. The sensor's measurement range has been chosen to help monitor the animal comfort zone and support fault conditions, if any, in barns heated by direct combustion. The sensor is protected by a robust housing and behind a carefully selected filter. The sensor comes with a cable and a cap to protect the sensor during washing and disinfecting. The sensor must be placed in the middle of the house. The distance to the floor must be at least 50 cm. However, the sensor must be set up out of the reach of the animals. Supplied with an M12 connector and blanking plug and protection cap for DOL 119. TECHNICAL SPECIFICATIONS
