PT03 Flush Diaphragm Pressure Transmitters

Pressure Transducers and Sensors


Model PT03 pressure transmitters with flush diaphragm foil strain gauge with high precision no cavity measuring diaphragm especially suitable for measuring the viscosity of the liquid. The product installation structure was optimized by using the improved makes the product has a good ability to resist vibration. Match with a variety of amplifier circuit with distinctive features such as anti-jamming high temperature resistant safety explosion-proof type etc. make the type is suitable for oil food and other measuring control occasions.



◎No cavity measuring diaphragm used for measuring the viscous liquid;

◎Improve optimization of the structure of circuit and installation improve the shock resistance and stability;

◎Optional waterproof direct connection.

Installation schematic (for reference) , thread the front seal

Installation Suggestion:

(1)This product can use M20 x 1.5 interface directly installed on the pipeline (or the container wall), thread the front-end when installation should add copper pad or nylon washer for front end face seal. And, without cavity pressure transmitter thread front end flat membrane sensing head can not touch installation part of the front and side wall. Otherwise it will affect the performance of the pressure transmitter.

(2)Should be used when measuring high temperature medium, pressure pipe or other cooling device, the temperature dropped to pressure transmitter using temperature range.

(3)When the outdoor installation, should try to put the transmitter in ventilated, dry place, avoid bright lights direct illuminate and wet, otherwise will make the performance variation or malfunction.

(4)If the transmitter output or output exception found after installation, please check:

1):Electrical connections are accurate, whether the firm;

2):Whether the power supply voltage is too low and the load resistance is too large.
