Product Description
TXZL12 electronic flow switch based on the thermal principle, the sealed probe contains two resistors, one of which is not
heated as the detection resistance and the other is not heated as the reference resistance. When the mecum flows, the heat on the heating resistance is taken away, the resistance value is changed, and the difference between the two resistors is used as the basis for judging the velocity. No moving parts, maintenance-free, easy to install, one type is suitable for a variety of pipe diameter requirements, switch volume continuously adjustable, very low pressure loss, compact structure, LED display flow trend and switch status.
