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


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.

infrared temperature sensor types


RS-WD-HW-* infrared temperature sensor can calculate the surface temperature without touching the object, and can measure the temperature of moving objects. The sensor has built-in temperature compensation with high accuracy. The shell is made of stainless steel, which is waterproof and dustproof. In the same environment, our infrared temperature sensor is more stable than other products on the market.

Advantages of infrared temperature sensor

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.

Don’t wear

No contact means no friction. Infrared sensors experience no wear and tear and consequently have longer operating lives.

Top brand

Renke is 15 years of the brand manufacturer for monitoring devices, we have advanced technology, and offer professional after-sales. Provide customized services.

Provide more detail

A non contact ir temperature sensor can provide greater detail during a measurement than contact devices, simply by pointing it at different spots on the object being read.

Add display

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

Delivery fast

We have a huge production scale, with a daily output of up to 50,000 pieces, in stock, and guaranteed delivery within 24 hours after payment.

How does infrared temperature sensor work?

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.

infrared temperature sensor details

Measuring distance

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.
