Eco Tx Pressure Transmitter

Eco-Tx Pressure Transmitter


The Differential Eco-Tx Pressure Transmitter is ideal for the monitoring and management of ventilation systems, and is the perfect compliment to the highly accurate Eco-Radial Flowgrid or X-Grid range. Each Eco-Tx can be supplied fully calibrated, and setup to measure pressure, velocity or flow, at your desired operation set point or can be supplied ‘as is’. The Eco-Tx uses proven and stable Hall Effect (Tx-M1) & Silicon Based (Tx-M2) sensor technology for accurate and reliable pressure sensing performance. They can be configured for either linear pressure output, linear velocity output or linear flow output, depending on the system requirements and it has dual current and voltage outputs allowing users to simultaneously take either a current or a voltage ouput to the building controller and have a local test circuit for verification of the output reading.
