One, product use and configuration:
In 1, the product is also called the temperature controller can be set seven kinds of alarm mode to monitor the temperature exceeds the upper limit alarm value, the high limit alarm relay, open exhaust fan, refrigerator and drop in a low-temperature room temperature, until the meet the requirements so far. In the monitoring to the temperature below the lower limit alarm value, the lower limit alarm relay action, open the heater, hot air blower, etc. the increase of greenhouse temperature, until it meets the requirements, applicable to the granary, grain, grain piles, communication base station, computer room, power distribution room, armory, archives, libraries, drug warehouse, warehouse, workshop, greenhouse, vegetable greenhouses and other places.
2, the product model: WDQ.
3, this product has built in room temperature sensor, can also be used in accordance with the use of other external type temperature sensor, wire length of about 1 meters, can increase the length of the lead wire.
(1) the temperature sensor for the temperature measurement, 200, and 600, the type WDC-D, is suitable for heat preservation box, oven, barn, cold storage, non corrosive gas or liquid etc..
(2) - 50 DEG C temperature 150 wall type temperature sensor, model: WDC-G, used room, warehouse etc..
(3) temperature - 200 DEG C to + 200 DEG C O 4 * 30MM micro temperature sensor, model: WDC-W for in a small space or liquid.
(4) the temperature of - 200 DEG C to 150 DEG C refrigerator cold storage, anti false alarm of refrigerator temperature sensor, model: WDC-B. Use is made of special material to prevent false positives temperature sensor, can prevent staff normal placing medicines or other items caused by "false alarm" phenomenon, applicable in refrigerators, freezers, cold storage and so on.
(5) temperature - 200 DEG C to 600 DEG C reaction kettle temperature sensor, model: WDC-F, using a stainless steel casing, acid and alkali for with corrosive gas or liquid.
(6) welcomed the purchase through a long metal tube puncture multi-point monitoring granary depot multi point temperature sensor (model: WDC-Dn) or reactor multi-point temperature sensor (model: WDC-Fn).
4, this product in the use of multiple, need to focus on management, remote monitoring and alarm, optional with 3 Road, 7 Road, 14 cable alarm, model: BY3, BY7, BY14.
5, welcome to buy the flash type wall temperature alarm, type: WDQ-MS.
6, welcome to intelligent wall type temperature alarm, choose to call alarm number: WDQZ.
7, welcome to GSM wall temperature alarm, choose to send text messages and call the police model: WDQG.
Two, technical performance:
1, the working way: can set seven alarm mode, in monitoring to temperature exceeds the upper limit alarm value and its upper limit alarm relay, open exhaust fan, a refrigerating machine, such as drop in a low-temperature room temperature, until the meet the requirements so far. In the monitoring to the temperature below the lower limit alarm value, the lower limit alarm relay, open the heater, air heaters, etc., raise the temperature in the greenhouse, until the meet the requirements so far.
2, monitoring temperature: - 30 DEG C ~ 70 C. Optional external temperature sensor up to 200 DEG C 600.
3, measuring accuracy: 0.2.
4, adjust the setting: can adjust the zero correction value and full correction coefficient, can be used as a reference to the meter, adjust the measurement value of the instrument, in the use of the same measurement results.
5, you can set seven different alarm modes: limit alarm, alarm limit, super interval alarm upper limit and lower limit, limit and upper return difference alarm, limit and the lower limit of the hysteresis of the alarm, the upper limit alarm and over the upper limit of a value after the second and then the police (upper limit alarm) and the lower limit alarm and super limit a value after the second alarm again (lower limit alarm) etc..
6, alarm output: 2 on-off signal, relay contact capacity is 5A. Welcome to build a 4 way switch quantity signal products.
7, alarm volume: less than or equal to 100 db.
8, support data transmission: external temperature sensor wire length can reach 300 meters.
