DS4

ADZ NAGANO DS-4 electronic pressure switch

Manufacturer: ADZ Nagano
Category: Pressure, SENSORS

He ADZ NAGANO DS-4 it's a programmable electronic pressure switch High precision, designed for pressure monitoring and control in hydraulic, pneumatic and industrial automation systems.
Made of stainless steel and with thin-film piezoresistive technology, it offers excellent long-term stability, high resistance to pressure spikes and high compatibility with aggressive media.

Switching points and hysteresis are easily configured using PC software, without the need for a reference pressure, simplifying field parameterization.
