1、 Product Introduction

The 1151GP capacitive pressure transmitter (gauge pressure) measures a minimum pressure of 1kPa and can be transferred to a negative pressure transmitter. Target audience: liquids, gases, and vapors.

The key raw materials, components, and parts of the ZRN1151GP pressure transmitter are all imported or jointly produced, and the entire machine has undergone strict assembly and testing. This product features advanced design principles, complete variety and specifications, and easy installation and use. Due to the complete integration of the structural advantages of the two most popular and widely used transmitters in China (Rosemount 3051 and Yokogawa EJA) in terms of appearance, this model provides users with a refreshing feeling and has strong versatility and substitutability. In order to adapt to the continuous improvement and development of domestic automation level, this series of products not only has a compact and exquisite design, but also introduces intelligent functions with HART fieldbus protocol.

Technical parameters

Target audience: liquids, gases; And steam

Power supply voltage: 12-36V DC, standard value 24VDC;

Output signal: 4-20mADC; (Special for four wire 220V AC power supply 0-10mA DC output)

Environmental temperature: -25~70 ℃ (typical transmitter), -15~70 ℃ (with on-site indicator)

Measurement temperature: -40-104 ℃, flange filled with silicone oil -40-104 ℃, filled with high-temperature silicone oil 15-315 ℃

Storage temperature: -40~100 ℃;

Relative temperature: 0-100% RH

Protection level: d Ⅱ BT4 ia Ⅱ CT5;

Power supply impact: less than ± 0.005%/V of the output range;

Vibration effect: Vibration at 200Hz in any direction causes an error of 0.05%/g of the maximum range (micro differential pressure of 0.25%/g);

Installation position impact: When the working diaphragm is not installed vertically, a zero position error of no more than 0.24Pa may occur, which can be eliminated by adjusting the zero position and has no effect on the range;

Stability: not exceeding the accuracy of the transmitter within six months;

Indicator: The on-site output indicator has an ammeter with a linear indication of 0-100%; 3-1/2 digit LCD display range and zero position: externally continuously adjustable;

Positive and negative migration: Differential pressure transmitter: maximum positive migration is 500%, maximum negative migration is 600%
