GMS Microwave level switch electrical isolation unit consists of three components: a transmitter, receiver and amplifier, transmitter and receiver each other in pairs. In order to obtain good performance need to ensure that the receiver, the transmitter is securely mounted and is a strictly positive right. The transmitter sends to the receiver's ability to detect the microwave having a microwave beam, the microwave beam is transmitted 200 times per second, when the microwave-absorbing material in the same plane as the receiver, the microwave beam will not reach the receiver, the receiver will not detect and therefore measured microwave beam.
When the receiver detects a microwave beam ends, the status change will be triggered when the relay. From the detected state to a series of microwave relay delay time length is set by two separately adjustable potentiometer; effective and a trigger signal for setting the relay, and one for the relay triggered interrupt signal relay The total movement in the signal state change
And to maintain the length of time after you have set. The delay period will cause any change in the status of the delay to start again.
By a receiver sensitivity adjustment potentiometer, after adjustment, and make the reflectivity of the absorption rate between the different materials to be compensated. Similarly, we have to adjust to be detected even if only part of the microwave beam can also change the trigger condition. There are two systems for sensitivity adjustment potentiometer, respectively, for coarse and fine adjustment. When the detected signal is interrupted, the relay status can be
Set energized or de-energized, this mode of the receiver side by binary switch settings.
Amp set up three LED indicators are used to indicate the power supply; valid signal; relay is energized. While the transmitter is only one indicator to indicate power supply.
