1151LT Flange type liquid level transmitter produced by SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD. The measured pressure of two kinds of media into the high and low pressure chamber, the role of δ elements (ie, sensitive components) on both sides of the isolation diaphragm, through the separator and the components of the filling fluid Transfer to both sides of the measuring diaphragm.

Introduction

Flange type liquid level transmitter is composed of measuring the diaphragm and the insulating chip on both sides of the composition of a capacitor. When the pressure on both sides of the inconsistency, resulting in displacement of the measurement diaphragm, the displacement and pressure difference is proportional to, so both sides of the capacitor capacity, through the oscillation and demodulation links, converted into a signal proportional to the pressure. Pressure transmitters and absolute pressure transmitters operate in the same way as differential pressure transmitters, except that the low pressure chamber pressure is atmospheric or vacuum.

The A / D converter converts the current of the demodulator into a digital signal whose value is used by the microprocessor to determine the input pressure value.

The microprocessor controls the operation of the transmitter. In addition, it performs sensor linearization. Reset the measurement range. Engineering unit conversion, damping, prescribing, sensor fine tuning and other operations, as well as diagnostic and digital communications.

The microprocessor has 16 bytes of program RAM and has three 16-bit counters, one of which performs A / D conversion.

The D / A converter fine-tunes the data from the microprocessor and the corrected digital signal, which can be modified with the transmitter software. The data is stored in the EEPROM, even if the power is also stored intact.

The digital communication line provides a transmitter interface with an external device (such as a 205-type intelligent communicator or a HART protocol control system). This line detects the digital signal superimposed on the 4-20mA signal and transmits the required information via the loop. The type of communication is frequency shift keying FSK technology and according to BeII202 standard.
