•
The °C display (LED 5) indicates the gas temperature in °C.
Switch output 1
•
Switch signal as the limit value for volume flow, hysteresis or
window function as NO or NC contact.
•
Pulse sequence for adjustable consumption quantity, e.g.
1 pulse/m³ (pulse length 100 ms) or quantity monitoring via pre-
set counter ( Setting the preset counter / pulse value (ImPS),
page 36).
Switch output 2
•
Switch signal as the limit value for volume flow, hysteresis or
window function as NO or NC contact.
•
Analogue signal (4 to 20 mA) for corresponding volume flow.

Based on the small size, the sensor only has a small
contact surface. The pressure loss is thus negligible
(typically 1 mbar).
