659系列 按鈕溫度傳送器

Series 659 按鈕式溫度傳送器 簡介

可程式化設定、支援 RTD/熱敏電阻/熱電偶輸入、內建式安裝
Series 659 按鈕式溫度傳送器可相容熱電偶（J、K、T 型）、RTD（Pt100Ω）或熱敏電阻訊號輸入，並轉換為線性化之 $4～20mA類比輸出。

一、快速校準： 透過內建單一按鍵即可快速完成量程設定與校準。
二、狀態診斷： 配備 LED 指示燈，即時顯示感測器故障與程式設定模式。
三、電路保護： 具備電源極性反接保護（Reverse Polarity Protection）。
四、訊號穩定性： 熱電偶型號具備電氣隔離（Galvanic Isolation）與冷端補償（Cold Junction Compensation）功能。
五、結構設計： 體積輕巧，可直接安裝於標準型式之感溫頭（Terminal Head）內。

​Series 659
Push-Button Temperature Transmitter
Programmable, RTD, Thermistor or Thermocouple Input, In-Head Mounting

Series 659 Push-Button Temperature Transmitters accept thermocouple (J, K, T), RTD (Pt100Ω) or thermistor input and provide a linearized 4 to 20 mA output. The transmitter is quickly ranged and calibrated by using a single on-board switch. An LED provides visual indication of sensor fault and programming mode. Models feature reverse polarity protection. Thermocouple models are also galvanically isolated and cold junction compensated.

The compact transmitter can be mounted directly within any standard thermal head for connection to the sensor. The Series 659 Transmitters are ideal for temperature measurement in boilers, burners, ducts, furnaces, refrigeration systems, food processing, tanks, chemical processing, steam generators or any other process application.
