Teledyne公司的1220微處理器控制的氣體檢測系統是專門設計用來監控諸如煉油廠，化工廠工業場所，以及潛在的爆炸性氣體和蒸氣的存在發出警告。
此外，1220可以激活通風或灑水系統或工藝設備關閉，直至被淘汰的危險。誰在與工廠人員利用氣體檢測儀器協作開發的，1220是一個融合了靈活性和國家的*先進的電子設備簡單。
優勢。
可靠的微處理器為基礎的電子產品。
1MAN校準。
沒有安裝電子領域的需要。
堅固，實地驗證探測器。
積木式設計原理。
幾乎每個應用都有其獨特的要求，以對一些地方開始由一個系統進行監控。因此，靈活性是在1220的設計的關鍵因素。一個1220系統是由一個中央控制站和遠程探測器。一個系統可以小或大如必要的，因為控制站的控制模塊采用了積木的概念，每個房子多達八個通道模塊連接到安裝在危險位置的一個或兩個探測器。
一項獨立的系統可以容納多達7個控制模塊，56通道模塊（圖3），112場安裝探測器。該探測器可以位于超過一英里，主要從系統。可選的只有AC或DC電源是需要系統**投入使用。

Model 1223 - 3 channel

The channel module is a stand-alone unit with its own microprocessor, power supplies, alarm relays, self diagnostics and controls. Easy to use and service, each channel module provides self diagnostics that automatically check power supplies, sensors, signal output and connections to insure key components are functioning properly.

Failure codes are provided to quickly locate troubles spots and assist in keeping the system on line at all times. The module can be easily re-configured to operate in the dual detector configuration by simply installing the S2 activation PC board. When installed, the microprocessor automatically reconfigures itself to accommodate the second detector.

Modifications to the channel module settings are protected by an optional pass code which prevents access to the SELECT key menus. Once the SELECT key is activated the menus are displayed. Successive key strokes advance the selection, and menus are prioritized based on anticipated usage.

Options

• T Two sensors per channel
• M 4-20 mADC output
• R RS-485 output (MODBUS Protocol )
• V 12-24 VDc operation

Detectors

Refined over the years, Teledyne’s rugged detector design has demonstrated exceptional performance under the harshest environments. Based on the low temperature catalytic oxidation principle, the detector utilizes stainless steel support bars in the construction of the platinum sensing beads which provide exceptional stability and long life under shock and vibration conditions.

During operation, the beads are heated by a constant current through the heating coils. Oxidation of the combustible gases at the catalytic active bead raises the beads. This temperature rise in turn causes the resistance of the coil to increase. Measurement of the change in the coil resistance produces an accurate measurement of the concentration of the combustible gas. The inert bead compensates for changes in coil resistance which might occur from other phenomena other than the combustible gas.

A wide variety of sensor configurations are available to meet specific application requirements including stainless steel sensor housings, lead or silicone resistance, and
