DPT (with 2 relays for 24 V)
Robust, universal, industrial-grade Δp - FILTER - CONTROL device with good long-term stability, very low temperature drift and high overpressure safety. 4 linear short circuit-proof analogue outputs 0-10 V, 2-10 V, 0-20 mA, 4-20 and 2 potential-free relay outputs for limit values max / min, are fitted as standard.
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.
