HD-E910 Mechanical Load Test Machine

2.1 Cooling System

1

The refrigerating system equips Germany Bock Compressor, and uses environmentally friendly refrigerant (R404a). Adopting binary low temperature circuit system design, it is convenient to use different compressors for work in different temperature regions.

2

Temperature control using P.I.D + S.S.R system coordinated control with the same channel. It has the function of automatic calculation, which can immediately modify the temperature change conditions to make the temperature control more accurate and stable.

3

High-precision controllers of temperature. The temperature performance is accurately set and displayed with a resolution of 0.1 ℃.

2.2 Temperature System

1

Temperature system using Nickel-chromium alloy high-speed heating electric wire;

2

High temperature system is completely independent;

3

The system using stainless steel tube built-in nickel-chromium alloy high-speed heating electric wire and high-temperature magnesium oxide powder, which has fast response and long life;

4

The temperature system is completely independent
