GUT745 ultrasonic level sensor is a combination of ultrasonic sensor, temperature sensor, ultrasonic servo circuit and transmitter circuit. It uses SMD components and ASC chip, which makes the circuit compact and concise. The circuit board is plated and has high stability and long-term reliability. Meanwhile, the shell uses NLEPF synthetic materials with sturdy texture and good acoustic property. The transducer can be used in most working condition sites. While fixing it on the liquid wall or instrument housing, there is no need tools such as screws, but a 68mm hole. It has the features of stabilization, easy installation and disassembly.
Combined ultrasonic sensor, temperature sensor, ultrasonic servo circuit and transmitter circuit.
Adopts SMD components, ASC chip and plated circuit boards, ensure the product with small volume but good long term reliability.
NLEPF compound material housing, endurable and with good acoustic property.
Suitable for most of sites and user friendly.
