Introduction

DTZ-450BG surface sensor calibrator system is mainly used to calibrate L-type sensors and surface sensors of various sizes and types, such as thermistors, film sensors, surface resistance thermometers, strip sensors, surface thermocouples, etc.

DTZ-450BG surface sensor calibrator consists of a controller and a heater. It is easy to operate and intuitive to display. Simply set the temperature to start heating. The temperature rises quickly and the multi-stage PID temperature control is accurate.

DTZ-450BG surface sensor calibrator has an effective use range up to 130mm in diameter, and has a communication interface, which can be selected to communicate with a computer.

Function

◆ Support RS-232 communication, can be equipped with communication software

The calibration temperature can reach 400°C, and the heating and cooling speed is extremely fast

The surface sensor calibrator has a good heating and cooling speed. It only takes 30 minutes to rise from room temperature to 400°C, and it takes 55 minutes to drop from 400°C to room temperature. It only takes 45 minutes to cooperate with the rapid cooling device, which greatly improves the work efficiency. .

The diameter of the calibration plane reaches 130 mm, which can meet the calibration needs of most surface temperature sensors

The plane diameter of the surface temperature calibrator reaches 130mm, which is enough to calibrate L-shaped sensors and surface sensors of various sizes and types, such as thermistors, film sensors, surface resistance thermometers, strip sensors, surface-mounted thermocouples, etc.

An external reference platinum resistance thermometer can be installed to reduce the uncertainty of calibration

In order to achieve the ultimate calibration accuracy, the design engineer specially reserved a thermometer socket at the bottom of the aluminum surface, a platinum resistance thermometer with a diameter of 3mm can be inserted as a standard for comparative calibration, which greatly improves the calibration accuracy.

Excellent temperature uniformity and surface finish on the calibration plane

Surface sensors are often difficult to calibrate because it is difficult to find a flat, uniform surface temperature source. The measuring surface adopts "aerospace composite material coating", which has high hardness, good wear resistance and high thermal conductivity, which can ensure that the calibrated sensor is in good contact with the surface temperature calibrator, thereby reducing the calibration uncertainty.

Accurate and stable temperature control, small overshoot temperature

The device provides a variety of parameter options for users to choose, including setting the PID parameters of three different temperature ranges of high, medium and low, the inflection point between different temperatures, and the alarm temperature.

The weight of the whole machine is about 12kg, compact and portable.
