Guangzhou Keyi Instrument Technology Co., Ltd.

Supply temperature inspection instrument, multi-point patrol display instrument, inspection instrument ◇??Product overview: ??Intelligent temperature inspection instrument is suitable for the detection, alarm and transmission output of ~ point temperature, and can be equipped with various thermal resistors and Thermocouple, various standard current and voltage signals. Each input channel of the imported high-quality aluminum alloy shell terminal block is equipped with surge and overvoltage protection. Each channel of the transmission output is isolated and strictly anti-interference designed to suppress fast pulse group interference and other electromagnetic interference generated by on-site relays, contactors, etc. The anti-interference ability reaches level 1 and the basic error is less than... , display range -~, thermal resistance signal display The resolution is . ℃. The thermocouple signal can be selected ℃ or . ℃ through parameters. The basic error of the transmission output is less than ± .· Each channel independently sets the input signal type and point alarm value. Each channel independently sets the digital filtering time constant to improve Display stable value. Each channel independently sets zero point and full-scale correction to improve system measurement accuracy. Unused channels can be closed at will.

The graduation numbers inside the instrument include:,,,B,B,3. All channels are thermocouples. The graduation numbers inside the instrument include: BB. All channels are ~ or ~ and other current and voltage signals. When ordering, you need to specify that the input channels for current and voltage signals are thermal resistors and mixed thermocouples. The input channels are thermal resistors and thermocouples, ~, ~, ~, ~ are mixed. It is necessary to specify the input channels of current and voltage signals when ordering.
