Characteristic
By comparison with traditional XC series moving-coil instrument and common TE series analog instrument, S series digital temperature regulator has the unique advantages of high precision, good shock resistance, clear reading & error-free, long distance inspection and better reliability. The product has multiple adjusting forms of two-position, three-position, time proportioning, controlled silicon continuous adjustment and PID, and can increase transfinite alarm contact output function, is an upgrading product of XC series instrument. It is widely applied to the temperature measurement and automatic control of instrument in the industry of metallurgy, textile, plastic machine, incubator, baking oven, refrigeration chemical industry and medical care within the range of -200～1600℃. And it can display and control the parameter of pressure, flow and fluid level as it equips the corresponding sensor. Technical parameter

1、Installation maintenance
1）、There should be no corrosive gas on site and good connecting point contact.
2）、Should examine the instrument is properly cabled and the temperature-sensing component goes well with instrument index number before power is on.
3）、The mounting location of sensor should reflect the rise and fall of furnace temperature correctly and promptly.
4）、The connection between thermocouple and instrument should use corresponding compensating lead or directly connect to the instrument and the polarity cannot be opposite.
5）、If the instrument displays abnormal, should check whether the thermocouple connection is shorted or turned-off and whether the instrument working voltage is normal.
6）、The environment of instrument storage should meet the technical requirement.
7）、When the instrument is used measuring control of pressure, flow and fluid level, the name, model and specification of equipped component should be informed.
8）、Our company can provide favorable various specifications of sensors, such as thermocouple and resistance.
