Perforation type current temperature sensor price recommended source 'the long-term effective information'

Current temperature sensor input and output connection mode have?

（ 1) PCB pin welded installation: both on line, on circuit board will be welded on the circuit board, temperature sensor as a component. Its advantage is small size, light weight, saving space, easy to install.

（ 2) Screw fastening type installation: the temperature sensor with a screw on the bottom of the box or a fixed position, external connection is a variety of terminal lead connection. The optimal point is strong, convenient, easy to remove.

（ 3) Guide rail type installation: both at the bottom of the temperature sensor has a standard 35 mm wide dovetail groove, can be installed in a cassette. Its advantage is convenient, the versatility, suitable for field makes installation industry.

the current temperature sensor anti-interference

electromagnetic field

closed loop hall effect current temperature sensor, the use of the original edge the electromagnetic principle of wire. Thus the following factors directly affect the temperature sensor is affected by external electromagnetic interference.

( 1) Temperature sensor near the external current size and current frequency change;

( 2) Outer conductor and the distance of the temperature sensor, the external shape, location, and the temperature sensor of the wire inside hall of electrode position;

( 3) Installation temperature sensor used by material with and without magnetic;

( 4) Temperature sensor is used by the current block;

in order to minimize the interference of external electromagnetic field, according to the installation guide to install the temperature sensor.

current temperature sensor in the control and protection of the door into the system, the application of

the door into the system must provide security and protection for the users. Imagine a garage door locked people or cars in consequence. Current measurements can provide this kind of protection function.

electronic systems control garage doors, shutter and awning is gradually into People's Daily lives, and the protection performance is the most important function of must be taken into account when designing these systems. Current measurements can provide this kind of protection function.

used in garage doors, doors, shutters and awning on dc brush motor, at every time of normal opening and closing to produce its own repeatability of current distribution. The current waveform can be stored in the microcontroller. Current temperature sensor can provide dc brush motor current feedback at work, the door into the system manufacturer defined tolerance range, to that of the current waveform is stored in the microcontroller in the comparison. If the values do not match, the security problems. Micro controller will be alert and closed system or reverse rotation motor, to close the door again. The obstacles, person, or other object provides protection, at the same time protect the motor from damage caused by high current.
