Application
Differential pressure and volume flow transducer for monitoring differential pressure and volume flow of air and other nonflammable and non-aggressive gases. Three types with eight different measuring ranges are available for different applications.
In addition to differential pressure all variants provide the calculated volume flow as second analog output signal. K-values for
flow calculation (default 1500) can be parameterized via Thermokon USEapp. With the option board relay two-point controllers or
a 2-stage 2-point controller for differential pressure or volume flow can be realized. The mounting base (included in delivery)
allows mounting on a level surface or mounting on DIN rail TS35 (35x7,5 mm) according to EN 60715.

Mounting Advices
Before installing the device, please check the leak tightness of the pressure lines.
A prerequisite for the operation is a proper installation of all electrical supply, control and sensing leads as well as the
pressurized connection line.

Further calculation formulas, fan manufacturers and k-values can be selected via the USEapp.
Automatic Zero-Point Calibration - (optional)
Transmitters equipped with the auto zero calibration are maintenance free.
The auto-zero calibration electronically adjusts the transmitter zero every 10 minutes. The function eliminates all
output signal drift due to thermal, electronic or mechanical effects. The auto-zero adjustment takes approx. 4
seconds after which the device returns to its normal measuring mode. During the 4 second adjustment period, the
output and display values will freeze to the latest measured value.
Manual zero-point calibration (for devices without auto-zero function)
In normal operation zero point calibration should be executed every 12 months.
Attention! For executing zero point calibration the power supply must be
connected one hour before.
• Release both connection tubes from the pressure terminals + and • Press the button until the LED lights permanently
• Wait until the LED flashes again and reinstall the connection tubes to the pressure
ports (note + and -)
Configuration
The Thermokon bluetooth dongle with micro-USB is required for communication between
USEapp and USE-M / USE L (Item No..: 668262). Commercial bluetooth dongles are not
compatible.
