Instrumentation / Primary instrumentation (flow, temperature, level and pressure)

The NAH 8254 pressure switch with 1 or 2 switching outputs and a high accuracy of 0.3% features a thin-film-on-steel sensor cell offering exceptional long-term stability with triple overpressure safety (5-fold option also available). The robust design and wide temperature range of -40°C to +125°C make the NAH 8254 the ideal solution when an accurate and reliable switching signal is required in harsh environmental conditions.
