910风道温度传感器-变送器





温湿度传感器-变送器

910风道温度传感器-变送器提供了0-10V DC 输出、4-20mA 输出及电阻输出等多种形式。 可用于对环境温湿度有较高要求的场合,已在电子厂、制药厂、卷烟厂、印钞厂、程控交换机房等多种工业厂房环境得到应用。

结构:

910风道温度传感器-变送器,由高精度厚膜铂电阻感温元件及其电压(电流)变送电路构成温度检测电路。当温度变化 时,铂电阻阻值随之变化,检测此变化值,将其转换成电压(电流)信号。通过标准端子输出。湿度检测采用高分子薄膜湿敏电容,当湿度变化时电容值发生变化。 将其转换成电压(电流)信号,通过标准端口输出。
传感器封装在经特殊设计能够均匀检测到温湿度变化的壳体中,并充分考虑到器件本身散热对测量精度的影响。可方便的安装在风道壁上。

安装:

实际上风道温湿度传感器可以安装于任何位置,安装时请依照下列指示:
1、将传感器置于具代表性的位置。
2、传感器不应直接受阳光或其他的照射(如灯、辐射等)以避免导致测量误差。
注:该传感器不可用于腐蚀性气体的环境,否则将对湿度探头造成不可修复性损害

T40 Rattler Single Gas Monitor
The T40 Rattler is a low-cost, maintenance-free single gas monitor designed to protect personnel from dangerous hydrogen sulfide or carbon monoxide gas exposure in the most extreme conditions. Despite its compact size, the T40 Rattler includes features usually found only in larger multi-gas monitors – including a large, liquid crystal display (LCD), internal vibrating alarm, audible/visual alarms and simple push-button operation. The monitor continuously displays ambient CO or H2S readings in PPM and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. The T40 Rattler also has a peak/hold feature to show the highest reading during a shift and includes a patented fl ip-cap calibration adapter for quick and simple calibration. The T40 Rattler operates for up to 1,500 hours on a single “AA” battery (included) and is covered by a two-year warranty from the date of manufacture.
