Description

Robust, universal, industrial-grade Δp - SENSOR - TRANSMITTER with good long-term stability, very low temperature drift and high overpressure safety. 10 linear short circuit-proof analogue outputs 0-5 V, 0-10 V, 2-10 V, 0-20 mA, 4-20 mA or inverse: 5-0 V, 10-0 V, 10-2 V, 20-0 mA, 20-4 mA and 3 potential-free relay outputs, e.g. for limit values max and/or min, are fitted as standard (4th relay output available as an option). Universal supply voltages: 110-120 VAC, 230-240 VAC and 24 VDC. Small IP65 housing in a shapely design.
 

Examples: Ventilation and air-conditioning units, medical technology, clean room technology, filter control, fill level control and regulation, flow detection system, etc.

For ventilation applications with the ever present turbulence, a programmable Δp damping of the display and outputs is a necessary functional advantage.
