Thank you for visiting our product information. Our company is customer-centric, and whether you are inquiring or purchasing, we will be dedicated to serving you.

1、 Product Overview:

Our digital display deviceUsing microprocessors for control operations, isolation design, and jumper free technology, it can perform linear correction on various nonlinear input signals. It can be used in conjunction with various sensors to display, alarm, and transmit measurement signals such as temperature, pressure, liquid, flow rate, and speed.The instrument has functions such as universal signal input, disconnection alarm, over range indication, self calibration, and self diagnosis. The serial communication output provided can communicate bidirectionally with various devices with serial input/output, forming a network control system.

2、 Instrument features:

After years of on-site verification, this instrument has the following characteristics:

1Due to the use of large-scale integrated circuits, the structure is simple and the lifespan is longer. No flying wires, no adjustable potentiometers, all functions are completed by software.

2The high-speed sampling of the input signal 50 times per second enables this instrument to have higher accuracy, more stable performance, and stronger anti-interference ability compared to similar instruments. Six categories and nearly a hundred levels of anti-interference modes that can be set by users themselves enable this instrument to adapt to various working environments under different conditions; Capable of high-precision isolation and transmission output; The instrument's self fed DC 24V constant voltage source can meet the needs of various two-wire transmitters. Calibration is handled by software, and some parameters can be calibrated on-site.

3It can achieve 8 types of thermocouples, 5 types of thermal resistors (small range Pt100X), 5 types of linear voltages, 3 types of linear current inputs, and 1 type of frequency input signal.

4Linear input instruments can be calibrated on-site using shortcut keys, making them particularly suitable for remote pressure gauges.

5Peak holding function.

6It can achieve five switch outputs, four position alarm output ports, and can be configured with various alarm methods such as upper and lower limit alarms, OK alarms, absolute value alarms, and associated alarms. It can also monitor and output alarm points. Special wire breakage alarm function, when wire breakage alarm occurs, the instrument will automatically lock the output state before the alarm.

7By setting password protection in the menu, different levels of protection can be achieved

8The optional two-way time timer can time parameters such as alarm time and output time, and can be combined with the temperature control part to achieve automatic logic control.

9The RS485 communication port with high reliability and fast response adopts the CRC-16 verification core of the American data communication standard, which can realize communication methods such as multi host, single host, and no host.
