SDE-P: Air Differential Pressure Controller and Sensor

SDE-P

Compact air differential pressure transmitter with high sensitivity

The SDE-P is a programmable differential pressure transmitter. The transmitter measures the pressure by the use of a diaphragm that transfers the force onto a ceramic fulcrum lever. The signal is a temperature compensated and calibrated. The microprocessor samples the pressure once per second. It calculates an averaging signal over a preset number of seconds and generates an output signal based on minimum and maximum pressure values.

Applications

Pressure measurement in the field of heating, ventilation and air conditioning
Measuring of air flow velocity
Measuring and control of positive or negative pressure for example for clean rooms
