Abstract
The utility model relates to a detection device of a temperature-sensitive cable and aims to automatically control detection temperature by using a closed loop temperature control device. The detection device is characterized in that a dc power supply (1) is connected with a temperature controller (2), the temperature controller (2) is connected with a heating plate (3), and a temperature-sensitive probe (4) is fixed on the heating plate (3) and is connected with the temperature controller (2). The device can automatically adjust temperature at a set value, no open fire exists, and the temperature can be controlled within 150 DEG C, so no matter the detected temperature-sensitive cable is in an inflammable and explosive environment or not, the device can detect the performance of the temperature-sensitive cable. Because a safe voltage is adopted for the structure of the device, so the device is always safe.
Description
Affiliated technical field:
The utility model relates to a kind of pick-up unit of temperature sensing cable.
Background technology:
Traditional detection method is to adopt the way that hair dryer or hot water drench to carry out, and does both lack of standardizationly, inaccurate again like this, can not satisfy the standardization requirement of engineering detecting.
Summary of the invention:
The purpose of the utility model provides a kind of device that temperature sensing cable is carried out accurately again the detection of standard ground.
The utility model can be realized like this: a kind of pick-up unit of temperature sensing cable; It is characterized in that: direct supply (1) is connected with temperature controller (2); Temperature controller (2) is connected with heating board (3), and temperature-sensing probe (4) is fixed on the heating board (3), is connected with temperature controller (2).Temperature sensing cable to be detected is placed on the heating board; To heating board (3), temperature-sensing probe (4) is that signal is passed temperature controller (2) back with the temperature inversion of heating board to the safe DC current that low-voltage dc power supply (1) produces, when temperature rises to the set temperature value (or a little higher than set temperature value) of temperature controller (2) through temperature controller (2); The temperature detect switch (TDS) of temperature controller (2) cuts off DC current; Then heating board (3) stops heating, and when heating board (3) when temperature is lower than set temperature value, the temperature detect switch (TDS) of temperature controller (2) is connected DC current; Make heating board (3) continue heating, thereby control the temperature of heating board (3) so repeatedly.The temperature of above-mentioned heating board (3) is the temperature sensing cable to be detected current supply circuit of the monitoring design temperature place that produces fire just.
The utility model has solved safe, convenient, the harmless needs that temperature sensing cable detects.
The utility model can be perfect like this: dc charger (5) is connected with direct supply (1).The effect of dc charger (5) is for the charging of this pick-up unit, to guarantee its normal use.
The beneficial effect of the utility model is; Adopt this structure because device is automatically regulated temperature at design temperature, and do not have naked light, Controllable Temperature is in being no more than 150 degrees centigrade scope; So no matter whether temperature sensing cable to be detected is in inflammable and explosive ambient condition; All can carry out the performance of temperature sensing cable is detected, and because this structure adopts is safe voltage, under device is in a safe condition all the time.
