Tek-Trol 3120A-G-5-FM-1-1-LCD 0-725 pis Pressure Transmitter

Tek-Trol, 3120A-G-5-FM-1-1-LCD, 0-725 pisg Explosion-Proof Multifunctional Gauge/Absolute Pressure Transmitter with Integrated LCD Display

Features:

• The operator can calibrate the device using a zero/span button, no handheld calibrator is required.
• Digital communication HART^® protocol, the latest version
• Fail-safe mode process function for detecting any abnormal condition that occurred
• Automatic ambient temperature compensation improves the performance of the device
• It can be used as a flow meter and should be installed vertically without using additional flanges
• Various Output: 4-20 mA, digital signals
• The mounting bracket can be rotated up to 360º and LCD up to 270º
• EEPROM write protection
• ±0.075% accuracy, the most accurate sensor in the industry.
• The software of the transmitter compensates for the thermal effects, improving performance.
• Precise Input Compensation during operation is achieved with temperature and pressure correction coefficients that are characterized over the range of the transmitter and stored in the sensor module EEPROM memory.
• EEPROM stores sensor information and correction coefficients separately from the MCU module, allowing for easy repair, reconfiguration, and replacement

Applications:

• Water and wastewater
• Oil and Gas
• Pulp and paper

The Tek-Bar 3120A series of smart transmitters have excellent stability, and high accuracy, and include features that facilitate easy installation, start-up, and minimum maintenance thereby lowering process downtime and the overall cost of ownership in the long run. These transmitters are equipped with an automatic temperature compensation function integrated into their advanced signal processing circuitry to ensure high reliability and performance corresponding to the change of ambient temperature.

Measuring Principle

The Tek-bar 3120A uses a piezo-electric pressure transducer. It consists of quartz crystal, which is made from silicone and oxygen arranged in a crystalline structure (SiO2 ). That crystal is inserted between a solid base and the pressure-sensing diaphragm. If pressure is applied, the same force will fall on the pressure-sensing diaphragm that pressure to stretch or bend the crystal, and an electric potential is generated. The voltage produced will be proportional to the magnitude of the applied pressure.
