DWYER差压开关1950系列技术参数

SERIES 1950 EXPLOSION-PROOF DIFFERENTIAL PRESSURE SWITCH

Compact, Low Cost, Explosion-proof and Weatherproof

Series 1950 Explosion-Proof Differential Pressure Switch combines the best features of the popular Dwyer® Series 1900 Pressure Switch with an integral explosion-proof and weatherproof housing, making it an exceptional value for either application. It is CE, UL and CSA listed, FM approved for use in Class I, Div 1, Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres (NEMA 7 & 9), Raintight NEMA 3 (IP54). Weatherproof features include a drain plug and O-ring seal in cover. Electrical connections are easily made by removing front cover. For convenience the set point adjustment screw is located on the outside of the housing. Twelve models offer set points from .03 to 20 in w.c. (0.0075 to 5 kPa) and from .5 to 50 psi (0.035 to 3.5 bar). The unit is very light and compact — about half the weight and bulk of other explosion-proof or weather-proof switches with separate enclosures.

1950系列防爆压差开关

紧凑、低成本、防爆和防风雨

1950 系列防爆差压开关结合了流行的 Dwyer® 1900 系列压力开关的最佳特性和一个完整的防爆和防风雨外壳，使其成为这两种应用的卓越价值。它已通过 CE、UL 和 CSA 认证，FM 批准用于 I 类、Div 1、C 和 D 组、II 类 E、F 和 G 组以及 III 类危险环境（NEMA 7 和 9），防雨 NEMA 3（ IP54）。防风雨功能包括盖上的排放塞和 O 形密封圈。拆下前盖即可轻松进行电气连接。为方便起见，设定点调节螺钉位于外壳外侧。十二个型号提供从 .03 到 20 英寸 w.c. 的设定点。（0.0075 至 5 kPa）和 0.5 至 50 psi（0.035 至 3.5 巴）。该装置非常轻巧紧凑——重量和体积大约是其他带独立外壳的防爆或防风雨开关的一半。
