Digital intelligent sensors can be arbitrarily combined, plug and play, and the controller can be recognized automatically. It can be customized for single-parameter, double-parameter, and multi-parameter controllers, which can save costs better.
Automatically read the internal calibration record of the sensor, and replace the sensor without calibration, thus saving more time.
New circuit design and construction concept, low failure rate, strong anti-interference ability.
IP65 protection level, applicable to indoor and outdoor installation requirements
