FH Capacitance Pressure Transmitter General Introduction

Overview

FH Series Digital Intelligent Pressure/Differential Pressure Transmitter is a multipurpose digitalized intelligent instrument developed by FTD Automation Instruments., including capacitance pressure /differential pressure transmitter and direct-coupled pressure/fluid level transmitter. It is made on the basis of the mature and dependable sensing technology, combining the advanced single-chip computer technology and sensor digital exchange technology.

16-bit single chip is adopted as its core element, with its powerful function and high-speed calculation capacity ensuring the excellent quality of the transmitter. The whole design frame focuses on its dependability, stability and high precision and intelligentization, meeting the growing demand in on-site industrial use. To get this goal, digitalized signal processing technology is used in the software to ensure its disturbance capacity and zero point stability. Meanwhile, it has the Zero Stability Capacity (ZSC) and Temperature Supplementing Capacity (TSC).

The powerful interface functions guarantees an excellent interactivity with no need of manual operator. Its digitalized meter head can display 3 physical parameters including pressure, temperature and current, and 0-100% analogue indications. Keystroke operation can finish the basic settings of zero transfer, range setting, damping setting under the circumstance of no standard pressure, greatly convenient for the on-site debugging.

FH series digitalized Intelligent Pressure/ Differential Pressure Transmitter has the optional HART module. After the transmitter is added the HART module, it has HART communication capacity, with the conventional operation being controlled with the general manual operator. The special communication equipment and software provided by our company can operate the marking and temperature supplementation actions.

FH series digitalized Intelligent Pressure/ Differential Pressure Transmitter can be widely sued in the sectors such as petroleum, chemical, iron & steel, power supply, light industry and environmental protection, capable of realizing the measurement of various pressures, differential pressures, flows and fluids, adaptable for all kinds of harsh and hazardous environment and corrosive agents.

Features

High accuracy No mechanical and movable parts, little maintenance work Span and zero continuous and adjustable from outside Good stability Positive shift amount to 500%; Negative shift 600% Two-wire system 4~20mA DC Damping adjustable, overpressure protection Solid components, patch-type printed circuit board Explosion-proof structure, all-day use Unified structure, strong interchangeability of parts Miniaturization(total height 166mm) Diaphragm materials of contacting mediums option (316L, TAN, HAS-C, MONEL, etc.) smart HART protocol

Working Principle

Pressure or differential pressure will cause some changes in the sensor resistance value and the output value of bridge voltage. Through A/D conversion, it will change into the digital signal which is sent to the microprocessor for calculation; then a current control signal will be output to the current control circuit, converted into analogue 4-20mA current output. Meanwhile, the microprocessor is responsible for the interactive and other actions (display and setting).

FHDP/GP Differential Pressure/Pressure Transmitter with Remote

Diaphragm seals

FHDP/GP Differential Pressure/Pressure Transmitter with Remote Diaphragm seals provides a kind of reliable measuring way to avoid the measured medium from directly contacting with seal diaphragm of the transmitter. Transmitters with Remote Diaphragm seals are suitable for the following operation conditions: Mediums with high temperature should be isolated with transmitter. Measured mediums have corrosion to transmitters. Suspending liquid or mediums with high viscosity Measured mediums solidize or crystalize due to change of environment or technological

process temperature. Strict purification of measuring head is needed for replacing measured mediums Measuring head must be kept clean and sanitary. Pressure measurement of sealed container
