How to control the walk-in high and low temperature laboratory
The base of the walk-in high and low temperature test chamber adopts a channel steel welded net frame, so that it can bear the weight of the chamber body and the personnel specimen under the horizontal condition without causing unevenness and cracks on the bottom of the chamber body. The chamber body is divided into six chambers and a double or single opening door. The material of the chamber body is high-quality stainless steel plate for the inner bladder, the outer bladder is high-quality color steel plate, and the thermal insulation medium is polyurethane rigid foam for heat insulation. Lightweight, resistant to impact, and good heat insulation. The gate material is also made of color steel plate, and the gate handle is open inside and outside, so that the tester can open the gate freely from the enclosed room.
The high and low temperature laboratory adopts a unique balance temperature and humidity adjustment method to obtain a safe and accurate temperature and humidity environment. It has stable and balanced heating and humidification performance, and can perform high-precision, high-temperature temperature and humidity control. Equipped with a high-precision and intelligent temperature regulator, the temperature and humidity system adopts a color LCD touch screen, which can carry out various complicated program settings. The program setting adopts a dialogue mode. The operation is simple and rapid. The refrigeration circuit is automatically selected. The set value of temperature automatically selects the performance of the operating refrigeration circuit, realizing direct start-up refrigeration and direct cooling under high temperature conditions. The gate is equipped with a large observation window, which can facilitate the observation of the test state of the test sample. Equipped with multiple protection devices to effectively ensure the safety of the equipment.
How to control the walk-in high and low temperature laboratory, and what are the characteristics of its control system?
It adopts liquid crystal (LCD) to display the touch screen screen, which is easy to operate and easy to edit. The operation interface of the controller is equipped with Chinese and English characters for selection, and the graph of the timely operation can be displayed on the screen. There are multiple sets of program strings, each of which can be connected to multiple sets of procedures, and multiple sets of subroutines can be set for looping in each set of procedures.
With P.I.D automatic calculation function, the temperature and humidity change conditions can be corrected immediately, so that the temperature and humidity control is more accurate and stable.
It has Rs232 communication interface and connection software to monitor the test process and perform functions such as switching on and off.
With nine-point fault message display, if an abnormal condition occurs during operation, the power supply will be cut off immediately, and the cause of the fault will be displayed on the screen in real time.
The walk-in high and low temperature test chamber can provide temperature and humidity linear DC signal output to the temperature and humidity recorder to understand the status of the test conditions, thereby improving the reliability of the test.
