Multi parameter combination probe KR939SB4

Multi parameter combination probe KR939SB4It is a sensor that can simultaneously measure the vibration, temperature, and oil level of machine equipment. It can monitor the health status of machine equipment in real time, detect and eliminate possible problems in a timely manner, thereby maximizing the reliability and stability of the equipment.

Specifically, the vibration temperature oil level sensor mainly consists of the following three parts: 1 Vibration sensors: These sensors are used to measure the vibration of machine equipment and transmit the data to a data collector for processing and analysis.

2. Temperature sensor: This part of the sensor is used to measure the temperature changes of the machine equipment, provide real-time temperature data, and facilitate users to detect the thermal operation of the machine equipment.

3. Oil level sensor: This part of the sensor is used to measure the oil level height in the machine equipment and transmit real-time oil level data to the data collector.

The application scope is also very wide. For example, in the automotive industry, this type of sensor can be applied to the engine oil circuit to help monitor the health status of the car engine, detect parameters such as engine vibration, temperature, and oil level, and promptly identify and solve problems. In the mechanical industry, it can monitor the operating status of various machinery and equipment, such as fans, pumps, refrigerators, etc. Whether it is rotating or stationary equipment, this type of sensor can be applied. Vibration, temperature, and oil level sensors are three important industrial sensors that can help users achieve real-time monitoring and fault diagnosis of machinery and equipment, improve the operating efficiency and reliability of machinery and equipment. Realize real-time detection of device health status.

In short, the vibration temperature oil level sensor is a sensor with practical value. It can monitor the vibration, temperature, and oil level of machine equipment in real time, detect problems in a timely manner, reduce the occurrence of faults, and better maintain equipment. Meanwhile, the sensor is convenient to use, compact in structure, and can be widely applied in various industries and fields.

Multi parameter combination probe KR939SB4It is a non bus structure universal combination transmitter widely used in the safety monitoring system of cooling tower fans. This probe is capable of monitoring controlled equipment in all directions, which is a key safety operation indicator - mechanical vibration. It simultaneously completes high-quality vibration measurements in the X, Y, and Z orthogonal directions (in accordance with the International Organization for Standardization ISO-2372 standard) and measures the temperature of the lubricating oil inside the gearbox. The probe adopts a micro machining process vibration sensor originally from the United States. The vibration signal obtained by the sensor is then passed through a bandpass converter, a transformer, an amplifier, and a true effective value converter. Finally, the voltage/current drive circuit generates a 4-20mA standard current signal proportional to the vibration intensity. This probe integrates four two-wire 4-20mA transmitters that can be directly connected to computer data acquisition and control systems (DCS, PLC, etc.) for use. Main functions and technical parameters

Appearance and installation structure: The probe is a fully enclosed waterproof structure made of stainless steel, weighing about 0.6kg. The probe is in the form of an external thread and is installed in the threaded installation hole of the fan gearbox. The temperature probe rod is inserted into the gearbox. The thread specifications and probe insertion depth can be declared at the time of ordering.

Vibration measurement characteristics: (X, Y, Z three orthogonal direction indicators are the same)

Vibration measurement range: 0-20mm/s, measurement output is proportional to the true effective value (RMS) of vibration velocity, vibration measurement frequency band range: 10-1000HZ, comprehensive vibration measurement error: ± 1mm/s

Temperature measurement characteristics: Temperature measurement range: 0-100 ℃, comprehensive temperature measurement error: ± 2 ℃

Signal output characteristics: DC/4-20mA quasi two-wire output. Due to the limited number of probe wiring terminals, the positive power terminals of the four independent two-wire transmitters inside the probe are already connected internally, forming a+V terminal. If users need four independent two-wire outputs from the transmitters, they can request that the product be pre packaged with an 8-core shielded cable before leaving the factory for external output connection.

Power supply characteristics: working voltage: 40V, recommended working voltage: 24V, no-load working voltage: 15V (with built-in voltage polarity reverse protection), working current: 30mA per transmitter

● Load characteristics: Load resistance range: 0~1250 Ω (when supplying 24V), load resistance calculation (including transmission line internal resistance): Rmax=(V-15)/0.02 (where V is the supply voltage)

● Electrical connection: The probe is a 5-wire 6-terminal connection: 1 #+V:+24V power supply; 2 # GND: Connected to the casing and can be shielded; 3 # T: Temperature signal output; 4 # Z: Vibration signal output; 5 # Y: Vibration signal output; 6 # X: Vibration signal output. Users can connect in different ways according to the internal wiring principle of the probe. Please refer to the instruction manual [Figure 2] for the internal wiring principle diagram of the probe. When connecting the probe to the distributed computer measurement and control system DCS, refer to the instruction manual [Figure 5] and the wiring diagram of the DCS-AI input module. When connecting the probe to the programmable logic controller (PLC), refer to the instruction manual [Figure 6] and the wiring diagram of the PLC-AI input module.

Environmental characteristics: Environmental temperature range: -20~80 ℃, environmental humidity range: 0~100% (the outlet port is sealed with 704 silicone rubber)

Wiring and maintenance: The reference wiring specification is 5 × 0.3mm 2/RVVP type five core shielded cable, and the outer diameter of the cable seal should be between ￠ 5 and ￠ 7mm. Due to the high humidity environment inside the air duct, the cable must be strictly sealed with silicone rubber! The user customizes a pre packaged cable with a length of 10-15 meters from the factory, and during installation, the cable is led out to the external junction box of the air duct for connection. This probe can be used for a long time without maintenance.
