Guangzhou Keyi Instrument Technology Co., Ltd.

Supply temperature inspection instrument, multi-point patrol display instrument, inspection instrument basic performance ■ ~ input channels. Aluminum alloy shell, plug-in terminal blocks. ■ .Class accuracy, measurement and control speed .second or .second per channel (thermocouple channel). ■ Can input thermal resistance, thermocouple, DC current, DC voltage signals. ■ Bit channel number display, bit measurement value display, display range -~. ■ The display resolution of the thermal resistor is .℃, and the display resolution of the thermocouple can be set to ℃ or .℃ through parameters. (Each channel is set independently) ■ The total number of channels used can be set. You can also arbitrarily close channels that you don't care about temporarily so that they do not participate in tour display and alarm comparison. ■Each channel independently sets the signal type and range. ■ Each channel independently sets the digital filter time constant to improve display stability. ■Each channel independently sets zero point and full-scale correction to improve system measurement accuracy. ■ Equipped with fixed-point display function for easy adjustment. ■ Equipped with parameter copy function, parameter setting can be performed quickly, greatly reducing the workload of parameter setting. ■ Standard communication interface. You can choose R3 or II protocol or protocol. ■ Optional printing function. Manual, scheduled, and alarm printing can be realized. ■ Alarm function ① Each channel has an independently set alarm setting value and an independent upper or lower limit alarm method. ② Independent alarm indicator light for each channel. ③ Click alarm output, a settable alarm output mode. Mode: How the flash alarm works. Point alarm output: When any channel enters the alarm state from the non-alarm state, it closes automatically and delays recovery (confirmation) or panel button recovery (confirmation). Point 1 alarm output: closed as long as there is a channel in alarm state. The alarm indicator light of each channel has 3 states: ① Off: Indicates that the channel is in a non-alarm state. ② Flashing: Indicates that the channel enters the alarm state from non-alarm state, and there is no automatic delay confirmation or panel button confirmation. ③ Lights up to indicate that the channel is in alarm status and has been confirmed. Mode: The two alarm set points of each channel share the mode. Point alarm output: The point alarm set point of any channel is closed when it is in alarm state. Point alarm output: The point alarm set point of any channel is closed when it is in alarm state. 3rd point alarm output: The 3rd alarm set point of any channel is closed when it is in alarm state. Point alarm output: The point alarm set point of any channel is closed when it is in alarm state.

All channels are thermocouples. The graduation numbers installed in the instrument include: BB. All channels are ~ or ~ and other current and voltage signals. When ordering, please specify the input channel input of current and voltage signals. For mixed use of thermal resistance and thermocouple, input is for mixed use of thermal resistance, thermocouple, ~, ~, ~, ~. It is necessary to specify the input channel communication interface of current and voltage signals when ordering (Note) 3 interface interface b protocol R3 b protocol R Printing function (with hardware clock) (Note) Printing interface integrated printing (needs to be customized) (only for type instruments ) Instrument power supply ~ ~3 Non-standard function means non-standard function, there is no b communication protocol option that can be omitted -
