详细信息| 询价留言品牌：瑞士 TRAFAG 型号：8254 加工定制：否 类型：- 测量介质：- 测量范围：- kPa 精度等级：- 输出信号：- mA 电源电压：- V NAH 8254 – Hydraulic Pressure Switch
The hydraulic pressure switch NAH 8254 with 1 or 2 switching outputs and increased accuracy of 0.3% has an exceptionally long-term stable thin-film-on-steel sensor cell with triple (optionally 5-fold) overpressure protection. The robust design and the wide temperature range from -40°C to +125°C make the NAH 8254 the ideal solution when exact and reliable switching signals under rough environmental conditions are required.
