Application area
Calorimetric flow switch / transmitter for use in laboratory and plant
Product specification
Flow switch for low flow rates
Only a medium-contacting material
No movable parts (rotor) in monitoring medium
Analogue output
Low pressure losses
Very fast reaction times
The device is linearized and temperature-compensated
Integrated minimum limit switch, which is freely programmable
Functional description: In a compact design, the flow sensor combines the measuring tube and evaluation electronics that, according to the respective version, can control a settable limit value with a transistor output or an analogue output (4-20 mA or 0-10 V). The evaluation electronics records the flow speed by the temperature difference of two temperature sensors. The switching output is a push-pull transistor output and controls both PNP and NPN inputs. The function is designed as minimum contact.
