Non Contact Infrared Temperature Sensor

what is an infrared temperature sensor? The infrared temperature sensor can calculate the surface temperature of the object by measuring the intensity of the infrared radiation emitted by the target. Non-contact temperature measurement is the biggest advantage of infrared thermometers, allowing users to easily measure targets that are difficult to approach or move. We offer infrared temperature sensor RS485 and infrared temperature sensor 4 20ma two types.

About non contact infrared temperature sensor

Description

The RS-WD-HW-* temperature sensor is an integrated infrared temperature sensor. The sensor, optical system, and electronic circuit are integrated into a stainless steel housing. Easy to install, the standard thread on the stainless steel shell can be quickly connected to the installation site. At the same time, there are various options (various instruments, large screens, paperless recorder purge protective covers, laser sights, adjustable mounting brackets, etc.) to meet the requirements of various working conditions. RS-WD-HW-* non-contact infrared temperature sensor is an industrial infrared temperature sensor. This infrared temperature sensor range is -50℃~1200℃ for optional.

Features

RS-WD-HW-* IR temperature sensor can be used to measure the infrared intensity of the object so as to calculate its surface temperature without touching it. The built-in temperature compensation for the sensor greatly ensures the accuracy of the temperature measurement. The all-metal package of the sensor makes it able to protect against impact, water, dust, and so on. Given stable output data, our infrared temperature sensor can exhibit a much better measurement performance than most other similar products on the market.

Advantages of Renke infrared temperature sensor

IR temperature sensors read moving objects. Contact-based temperature sensors do not work well on moving objects. Infrared temperature sensors are ideally suited for measuring the temperatures of tires, brakes, and similar devices.

IR temperature sensors don’t wear. No contact means no friction. Infrared sensors experience no wear and tear and consequently have longer operating lives.

IR temperature sensors can provide more detail. An IR sensor can provide greater detail during a measurement than contact devices, simply by pointing it at different spots on the object being read.

Infrared temperature sensors can be used to detect motion by measuring fluctuations in temperature in the field of view.

The infrared temperature sensor can directly display the value with a digital display, that is, the infrared temperature sensor with display.

How does infrared temperature sensor work?

Infrared temperature sensor working principle

Any object radiates infrared energy and the radiation intensity changes with temperature. Infrared temp sensors use infrared radiation energy with a wavelength in the range of 8μm-14μm. The infrared temperature sensor is a kind of optoelectronic sensor, which receives infrared radiation and converts it into an electrical signal, and displays or outputs temperature through electronic circuit amplifier, linearization, and signal processing.

Measuring distance of infrared temperature sensor

The size of the measured target and the optical characteristics of the IR sensor determines the maximum distance between the measured target and the measuring head. In order to avoid measurement errors, the measured target should be as full as possible in the field of view of the probe. Therefore, the measured point should always be kept smaller than the measured object or at least the same size as the measured target.

Lens cleaning

The lens of the instrument must be kept clean to avoid measurement errors or even damage to the lens due to dust, smoke, and other contaminants. If the lens is dusty, wipe it with lens cleaning paper dipped in absolute alcohol.

Electromagnetic interference

In order to prevent electromagnetic interference, please try to keep the infrared temperature sensor away from electromagnetic field sources (such as electric motors, motors, high-power cables, etc.) during installation, and metal sleeves can be added if necessary.
