Capacitance Pressure / Differential Pressure Transmitters

DBCC3351 series intelligent and non-intelligent capacitance pressure / differential pressure transmitters are a new generation of capacitance series transmitter that are developed by Dandong Top Electronics Instrument Co., Ltd. on the basis of absorbing the merits from the like instruments manufactured in foreign countries and considering the practical applying occasions and features. They adopt popular European style in appearance shape and most maturely technical capacitance sensor core inside. They are suitable for process control and measurement in the fields of petrochemical, chemical, metallurgy, paper-making, textile, medical, electric power industry, etc.
Main technical parameters
Operating voltage: 24V DC
Precision: ÿ?.2%--ÿ?.5%
Input impedance: >100M¥¸
Suitable fluid: liquid, gas and steam
Measuring range: see table 1
Service voltage: 24V DC
Output signal: 4--20mA DC
Power entrance: M20ÿ?.5
Ambient temperature: -20--70ÿ?(for common transmitters)
-15--70ÿ?(for the transmitters with field indicators)
Power influence: less than ÿ?.005%/V of output range
Vibration influence: when vibration frequency at any direction is 200Hz, the error is 0.05%/g of the maximum range. Measuring code is 2. (for micro-differential transmitter, the error is 0.25%/g).
Load influence: when the power supply is stable, there is no load influence.
Mounting position influence: when the operating diaphragm is mounted vertically, zero system error is no more than 0.24kPa. This error can be removed through adjusting zero, there is no influence for measuring range.
Stability: Under the condition of temperature 28ÿ? the maximum static pressure 6.9MPa, the measuring ratio 1:1, the accuracy will maintain within ÿ?.2%FS during a whole year.
