PRODUCT OVERVIEW

PT303 economic pressure transmitter adopts diffused silicon pressure sensor as pressure sensing element. Through internal ASIC, the millivolt signal of sensor is transmitted into standard current signal. PT303 can be directly connected with computer interface card, control instruments, intelligent meters or PLC etc. conveniently. Long-distance transmission can use current output. PT303 features with small size, light weight. all stainless steel sealing structure and ability to work in corrosive environments. The product is easy to install and has extremely high vibration and shock resistance. PT303 is widely used in process control, aviation, aerospace, automobile, medical equipment, HVAC and other fields.

PERFORMANCE PARAMETERS

OUTPUT AND POWER SUPPLY

• Output: 4~20mA
• Power supply: 12~30V DC

ELECTRICAL CONNECTION & WIRING MODE

*All dimensions are in mm.

APPLICATION OF DAMPER

Applications
Cavitation, liquid hammer and pressure peak may occur in air or fluid systems with varying flow rates, such as the rapid closing of the valve or the start and stop of the pump.
Even at relatively low operating pressures, these problems may occur at the entrance and exit.

Media condition
In the liquid containing particles, nozzle clogging may occur. The vertical mounting of pressure transmitter minimizes the risk of clogging because the flow of fluid happens in initial start only, the volume of the rear of the nozzle is fixed and the nozzle has a relatively large aperture (1.2mm). The effect of medium viscosity on response time is small. Even if the viscosity reaches 100 CST, the response time will not exceed 4ms.

PRESSURE CONNECTION

*All dimensions are in mm.
NOTE: The torque depends on all kinds of factors, such as gasket material, kitting material, thread lubrication and pressure.
