Hart Capacitive 4-20mA Differential Pressure Transmitter (A+E-920C)
The Hart Capacitive Differential Pressure Transmitter adopts advanced integrated circuit and surface mounting technique. Compared with analog transmitter, the differential pressure transmitter has more functions like communication, test and configuration, etc. It has improved standard accuracy and temperature compensation to enhance the quality.
1. The differential pressure transmitter adopts advanced digital technique and frequency phase shift keying craft so that make the connection of site and control room more convenient.
2. Besides remote communication, the differential pressure transmitter possesses measuring range self-adjusted, zeroing button. The transmitter could be adjusted after mounted.

Different Pressure Transmitter Installation
The transmitter would be used to measure flow, level and other situation where need accurate pressure or differential pressure. Correct installation will affect the measured result. To get better performance, the transmitter should try to avoid great temperature change, impact and vibration conditions.
*Note: Measuring media must not be frozen. Otherwise the sensor would be damaged.
About CompanyAEAD Technology moves to Chinese first free trade zone --Shanghai Pilot Free Trade Zone in Nov. 2014. That is a milestone for the company development to global market.
AEAD Technology is committed to provide the very best support possbile. Our customers have unique service needs, and we offer a variety of service options to support them. For any questions, you will either get the answer or have one of our professionals to contact you within 24 hours.
Shanghai AEAD Technology Co., Ltd is a cooperation of Chinese and German technique which mainly performs in R&D, production and sales.
AEAD Technology was first founded in 2009 in Jiangsu, and established Shanghai Branch in May 18th, 2014. The new Shanghai factory would complete in DEC 2014, located in the Free Trade Zone.
