Abstract
The utility model relates to a sensor group, which comprises a sensor, a communication cable and an air pipe that are arranged in an insulation sheath, an air hose, sealant and a joint, wherein the sensor is arranged in a cavity of the joint and fixedly welded to with the cavity; a lead wire of the sensor is welded with the communication cable, and a heat-shrinkable pipe is arranged at the welding part; one end of the air hose is inserted onto a sensor air pipe of the sensor, and the other end of the air hose is inserted onto the air pipe in the insulation sheath; the lead wire of the sensor and the connecting part of the sensor air pipe and the air hose are sealed by the sealant. The sensor group has the benefits that the air-tightness and the durability of the sensor are improved; the welding point of the sensor lead wire and the communication cable is efficiently protected; a circuit part of the sensor as well as the air pipe and the air hose are hermetically packaged through the sealant, damage on a measuring circuit of the sensor due to the dewfall inside the sensor can be prevented, and the atmospheric interface of the sensor is smoothly communicated with the outer world.
Description
Technical field
The utility model relates to a kind of sensor module, and particularly a kind of throw-in type pressure sensor assembly is applicable to level gauging.
Background technology
The throw-in type pressure sensor assembly is direct and the contacted on-the-spot primary instrument of measured medium, is widely used in level gauging.Along with oil, the continuous development of industries such as chemical industry requires the resistance to corrosion of sensor module stronger, and sealing effectiveness is better, and permanance is better.
Summary of the invention
In view of the prior art situation, the utility model provides a kind of sensor module.The long-term use O-ring seal seal aging that is used to solve the liquid level sensor assembly causes the measuring media leakage problem, solves the sensor internal dewfall and causes short circuit to damage problem to sensor measuring circuit.
The utility model for realizing the technical scheme that above-mentioned purpose is taked is: a kind of sensor module; Comprise sensor; It is characterized in that: also comprise the telecommunication cable that is arranged in the insulation sleeve and snorkel, steam hose, fluid sealant, joint, said sensor places in the joint cavity fixing with the cavity welding, and the lead-in wire of said sensor welds with telecommunication cable; Weld is provided with heat-shrink tube; Said steam hose one end is inserted on the sensor snorkel on the sensor, and the other end is inserted on the snorkel in the insulation sleeve, and said fluid sealant seals up the lead-in wire of sensor and the junction of sensor snorkel and steam hose.
The effect that the utility model is useful: through structural change; Substitute the sensor measurement structure of rubber sealing with the argon arc welded seal; The sealing and the permanance of sensor have been improved; Effectively protect sensor lead and Capacitance Unbalance in Telecom Cables pad with heat-shrink tube, the circuit part of sensor and snorkel, steam hose encapsulate with fluid sealant, prevent that the sensor internal dewfall from causing damage to sensor measuring circuit; Steam hose is connected the snorkel of sensor with the cable that has air hole, the atmosphere contact that keeps sensor is with extraneous unobstructed.
