Precautions for the use of bimetal thermometer

When using the bimetal thermometer, the immersion length is generally controlled at 100mm. When the measurement temperature is in the range of 0-50C, the immersion length must be greater than 150mm. This is the only way to accurately measure the temperature.

What are the advantages of pressure transmitter

The pressure transmitter adopts intelligent chip, which has fast response speed and can react quickly to pressure changes. In the environment with large pressure changes or frequent pressure fluctuations, the advantage of the response speed of the pressure transmitter is more obvious, which can reflect the pressure change in time and effectively avoid the occurrence of production accidents.

Introduction to the application of the characteristics of temperature transmitter

A temperature transmitter is a meter that converts a temperature variable into a standardized output signal that can be transmitted. The temperature transmitter converts the physical measurement signal or ordinary electrical signal into a standard electrical signal output or a device capable of outputting in a communication protocol. The temperature transmitter is an instrument that converts the temperature variable into a standardized output signal that can be transmitted. It is mainly used for the measurement and control of industrial process temperature parameters. The current transmitter converts the AC current of the measured main circuit into the standard signal of the constant current ring and continuously transmits it to the receiving device.

Temperature Transmitter Features

Temperature transmitter applications: widely used in petroleum, chemical, metallurgy, electric power and other fields of pressure measurement and temperature measurement.

What is the difference between a thermocouple sensor and a thermal resistance sensor?

Thermocouple sensors are widely used in industry as contact temperature measuring devices. This is because the thermocouple has the characteristics of stable performance, large temperature measurement range, long-distance transmission of signals, and simple structure and convenient use. In order to help you understand, this article will summarize the relevant knowledge of thermocouple sensors.

Learn about pressure thermometers in one article

Pressure thermometer is a thermometer based on the principle that when an object is heated or cooled, its volume, length, area, etc. will change, which will cause pressure changes. This article will introduce the basic principles, characteristics, design principles and application scenarios of pressure thermometers, and look forward to its future development.

Pressure transmitter daily use matters needing attention

Do not apply a voltage higher than 36V to the transmitter, causing damage to the transmitter

Working principle of pressure transmitter

The intelligent pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas or steam, and then convert it into 4 ~ 20mA DC signal output. The intelligent pressure transmitter can communicate with the HART manipulator, through which it can be set, monitored or composed of a field monitoring system with the host computer. It is suitable for process control and pressure measurement in petroleum, chemical, metallurgy, electric power, light industry, textile, building materials, hydrogeology, food, medicine, environmental control and other industries.

Working principle and application of bimetal thermometer

The working principle of the bimetal thermometer is based on the principle of solid thermal expansion, welding two pieces of metal with very different expansion coefficients together. When the temperature changes, the very different expansion coefficients cause different expansion and contraction, resulting in bending deformation of the metal sheet. Different amounts of rotation are generated according to different deformations, and the amount of rotation drives the connected shaft and the indicator needle at the other end to indicate the temperature.

Principle of bimetal thermometer and matters needing attention in use

WSS series bimetal thermometer is a field detection instrument for measuring medium and low temperature. Bimetal thermometer is made of multi-turn straight spiral bimetal sheet. It is suitable for on-site detection of temperature in the ground range of temperature measurement. It can directly measure the temperature of liquid, steam and gas medium in the range of -80 ℃ ~ 600 ℃ in various production processes. The electric contact bimetal thermometer can automatically send a control signal to cut off the power supply or alarm when the working temperature exceeds a given value. It can replace the industrial glass mercury thermometer and can directly measure the temperature of liquid, steam and gas in the range of -80 ℃ ~ 500 ℃ in various production processes. Widely used in petroleum, chemical, machinery, shipbuilding, power generation, textile, printing and dyeing and other industrial and scientific research departments.
