Flow Switch

Thermal Electronic Flow Switches

Type: GE-327

Shell: Plastic

Probe: SS304

CE certificate
Product description: GE-327 Thermal Flow Switch is based on two temperature sensors, measured and compared to the temperature of the medium. The state of flow can be derived by the temperature difference.
ISO9001 ISO14001 ISO45001 CE ATEX

GE-327 Thermal Flow Switch is based on two temperature sensors which are positioned within the fluid medium. The unheated sensor registers the liquid temperature. the other sensor is heated a few degrees above the medium, when the medium flows, the heat generated in the sensor is conducted away by the medium. The temperature of the sensor is measured and compared to the temperature of the medium. The state of flow can be derived by the temperature difference.
