C-J18FNE/IDCU-MP-A(68) is a multifunctional pressure measuring device with multiple application fields. It is widelyused for high accuracy measurement of pressure, resistance, temperature and humidity in mining, chemical, energy, water supply and wastewater treatment engineering fields. This device can not only be used for online monitoring of parameters, but also for occasional laboratory tests.

C-J18FNE/IDCU-MP-A(68) is designed with a built-in microprocessor, and it is capable of accurately measuring pressure. It supports three types of measurement modes: digital communication, analog and isolated relay. The digital communication mode is connected to a host computer, where data can be transmitted through an RS-232 port between the device and the computer. The analog signal is transmitted to the display directly, and the isolated relay allows the device to send power on/off command signals. The device is also integrated with a LCD displaying interface, which can be easily operated by rotating the knob. Moreover, C-J18FNE/IDCU-MP-A(68) is capable of providing a variety of special functions, including data storage, calculating results, and even alarm setting.

The working principle of C-J18FNE/IDCU-MP-A(68) is based on the Wheatstone bridge. To measure pressure, the BJT (bipolar junction transistor) converts an electrical signal to a pressure-dependent signal. The signal is then sent to the analog output. The analog value is compared to the reference voltage by the differential amplifier, and the resulting difference is amplified by the amplifier. The amplified voltage is then converted to a digital value by the A/D converter and transmitted to the host computer via RS-232 port. The device is also integrated with over-current protection to protect the device from overload and voltage fluctuation.

In short, C-J18FNE/IDCU-MP-A(68) is a multifunctional pressure measuring device that can accurately measure pressure, resistance, temperature and humidity. It is designed with a Wheatstone bridge based measuring principle, and it is equipped with various special functions, such as data storage, calculating results, and alarm setting. Moreover, it can work in three measurement modes, which are digital communication, analog and isolated relay modes. All in all, it is an ideal solution for online monitoring or occasional laboratory tests in various engineering fields.
