Differential Pressure Transmitter

Differential Pressure Transmitter

Output: 4-20mA

Power Supply: 24VDC; No load, transmitter can operate at 12VDC; Maximum 45VDC

Accuracy: ±0.2%, ±0.25%, ±0.5% of calibrated span, including comprehensive errors of linearity, hysteresis, and repeatability.

Temperature Range: Amplifier operates at -29℃ to +93℃; Sensing element operates at -40℃ to +104℃;

Storage Temperature: -50℃ to +120℃;

Relative Humidity: 0-85%;

Positive and Negative Migration: Regardless of output, after positive or negative migration, the upper and lower limits of the span must not exceed the span's limits. Maximum negative migration is 600% of the minimum calibrated span, maximum positive migration is 500% of the minimum calibrated span.

The 335111513051 series capacitive transmitter features a variable capacitive sensing element that converts the capacitance difference between the measuring diaphragm and the capacitor plates into a standard signal through oscillator oscillation, modulation and demodulation, amplifier amplification, and voltage-to-current conversion. It can be used for measuring gases, liquids, and vapors.

The differential pressure transmitter offers high sensitivity, high accuracy, and strong overload resistance. Manufactured with imported sensors, the sensor and amplification circuit are highly integrated; housed in a die-cast alloy aluminum case with painted surface, the circuit zero and gain require no adjustment; strong anti-interference capability, resistant to acids and alkalis, ensuring long-term stability and reliability. Excellent stability, with long-term full-scale and zero stability up to 0.2%FS/year. Within the compensated temperature range of 0～70℃, temperature drift is below 0.2%FS, and within the entire allowable operating temperature range, it is below 0.5%FS.

Equipped with reverse polarity protection and current limiting protection circuits, incorrect installation of positive and negative poles will not damage the transmitter; in abnormal conditions, the transmitter automatically limits current to within 35mA.

 Solid-state structure, no moving parts, high reliability, long service life.

 Capable of high-precision measurement from air pressure to water and oil, unaffected by the quality of the measured medium.

 Easy installation, simple structure, economical and durable.
