Kanomax Remote Particle Sensors with analog output are designed to fit into your existing monitoring system, or they can be used as a stand-alone unit to monitor a critical area when connected to an alarm or controller. With two models available, these 2-channel remote particle sensors are capable of Modbus communication via RS485 interface. 0.1 cfm and 1.0 cfm flow rate models are available, along with flexible 4-20mA analog output with the 1.0 cfm unit (only).

These particle sensors output particle counts, error statuses and alarm signals, and are able to connect to a PLC or data logger for facility monitoring applications. They can be easily added to a process or building automation system. Fully compliant with ISO21501-4 calibration standard and JIS B9921.
