SDB温度表
SDB系列直感式温度表
SDB系列仪表通常用于监测气体压缩机的温度。发动机排气温度也可以监测,以表明重载或精益燃料混合物。SDB系列是一种直接安装温度装置。它提供了一个准确的直接读取表与可调限制开关,以激活警报和/或关闭。仪器前部的一个把手可以让你调整限制开关的跳转点。指针运动由双金属传感元件驱动。SDB系列最常见的用途是监测气体压缩机的温度。发动机的排气温度也可以被监控,以显示重载或精益燃料混合物,或使用SDB来帮助协调双引擎装置的载荷。

SDB系列直感式温度表
Direct Mount Temperature Gauges with Adjustable Limit Switch
The SDB Series gauges are commonly used to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate overloading or lean fuel mixtures.
- East-to-read dial
- Bi-metallic sensor
- Two temperature ranges
- Dials scaled in degrees Fahrenheit and Celsius
- CSA listed explosion-proof model available
The SDB Series is a direct-mounting temperature device. It provides an accurate direct-reading gauge with an adjustable limit switch to activate alarms and/or shutdown. A knob on the front of the instrument allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element.
The most common use of the SDB Series is to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate overloading or lean fuel mixtures, or use the SDB to help coordinate loads on twin-engine installations.

Optional Thermowells
Murphy offers thermowells (separable sockets) to facilitate maintenance of a temperature Swichgage instrument and to protect the temperature sensing bulb from extreme amounts of sys- tem pressure. For system pressures exceeding 285 psi (1.97 MPa) [19.7 bar] at 625°F (329°C) an optional thermowell is recommended for use with the SDB series.
The thermowell protects the SDB bulb from system pressures up to 3000 psi (20.68 MPa) [206.8 bar] at 300°F (149°C). Two thermowell options are available: 1/2 NPT and 3/4 NPT. Thermowells can be ordered with the SDB Series Swichgage instrument or ordered separately.
