Main feature
CX-PTB -928 series hydraulic pressure level transmitter main part is a capacity pressure transmitter with temperature and pressure compensation which is made of diffuse silicon or pottery and porcelain. It has two typeCX-PTB928 and CX-PTB928(S) which sort based on the size of the sensor. They use specific craftwork and have three protect functions inside which solve the problem of dew condensation. Measuring membrane tough the medium in large area, unease to locking, easy to clean. Father to exert the technical data of the resistant and the advantage of price. It adopt advanced digital circuit technical and have the function of the zero trace, linear compensation and temperature and pressure compensation. Display and Hart communication can be chose. It can be used in the deep water measuring, liquid measuring in tank, slot and hole, corrosive liquid measuring.

Connection diagram
In order to suit for the different specifically instrument,
XSTK pressure transmitter have many different electric apparatus connection types:
4～20mA output
1～5V output
Adjust and calibrate
Unscrew the bolts which are used to adjust the cover,
poke the cover and put the potentiometer adjusting hole
outside Z（Zero）zero adjusting range ±5%；S（Span）full range adjusting range 30%. If you need widely range
adjusting ,you can achieve zero 50% rise by the resistance on the
PCB board. Range move proportion is 10：1, potentionmeter can achieve 3：1 movement.
