Insertion 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 combined 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 extremes. 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 capacitor plates into a standard signal through oscillator oscillation, modulation-demodulation, amplifier amplification, and voltage-to-current conversion. It can be used for measuring gases, liquids, and vapors.

High sensitivity, high accuracy, strong overload resistance. Manufactured with imported sensors, the sensor and amplification circuit are highly integrated; uses a die-cast alloy aluminum housing with painted surface, circuit zero and gain require no adjustment; strong anti-interference capability, resistant to acids and alkalis, long-term stability and reliability. Excellent stability, long-term stability of full scale and zero point can reach 0.2%FS/year. Within the compensation temperature range of 0～70℃, temperature drift is below 0.2%FS, and below 0.5%FS across the entire allowable operating temperature range.

Equipped with reverse polarity protection and current limiting protection circuits, incorrect installation of positive and negative poles will not damage the transmitter, and 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.
