Product features

The16bit single chip microcomputer, high integration, good reliability.

Between the input and output, power supply and input, output are isolated from each other.

Software implementation of various thermocouple, heat resistance nonlinear correction, error <1%.

Using integrated temperature sensor thermocouple cold end temperature compensation, compensation of high precision.

Having broken alarm and the measured value, alarm function, and has the alarm indicating lamp.

With WDT functions. When the interference condition, program go fly, can be automatically reset. Has the work / inspection switch, which is convenient for the off-line checks.

A. can choose seven kinds of thermocouple in number one or 4in a thermal resistance.

B. can choose the index number range for range, lower limit setting.

C. can set measurement value, lower limit alarm.

D. can display real-time temperature field, showing the greatest number4.

Main technical index

Input signal: thermal resistance thermocouple signal or signals, DC millivolt signal.

Output signal: DC 4～ 20mA ( DC 1～ 5V )

The current output allows the load resistance:250 ～600 Ω

Basic error:2mV ≤<3mV range (3 Ω<ΔR<6 Ω) when± 1.5%

(3mV ≤<5mV≤6Ωrange is± 1%Δ R<10Ω)

Range≥ 5mV (Δ R = 10±0.5%Ω).

Working conditions:

Power supply voltage: DC24 ±10%V

Ambient temperature5～ 40 ℃:

Relative humidity:5%～ 85% no condensation

When the instrument found the machine fault diagnosis, a fault status signal output ( referred to as the event signal )
