Product Details

Overview

HP3351The series capacitive transmitter has a variable capacitance sensing element that can oscillate, modulate, amplify, and convert the capacitance difference between the measuring diaphragm and the capacitor plate into a standard signal through an oscillator, modulation and demodulation, amplifier amplification, and voltage and current conversion. Can be used for measuring gases, liquids, and vapors.

Main technical parameters

◆ lose Out:4-20mA

◆ electricity Source:24VDCNo load, the transmitter can work in12VDCThe maximum is45VDC

◆ essence Degree: ± of calibration range0.2%,±0.25%,±0.5%,The comprehensive error includes linearity, variability, and repeatability.

◆ Temperature range: The amplifier operates within-29℃-+93℃； Sensitive components work in-40℃-+104℃；

◆ Storage temperature:-50℃-+120℃；

◆ Relative humidity:0-85%；

◆ Positive and negative transfer: Regardless of the output, after positive and negative transfer, the upper and lower limits of the range must not exceed the limit of the range. The maximum negative transfer is the minimum calibration range600%The maximum positive migration is the minimum calibration range500%.
