PT1151 Digital Intelligent pressure transmitter

Based on the world's advanced, mature and reliable capacitive sensor technology, PT series products are elaborately designed with the combination of advanced monolithic computer technology and sensor digital conversion technology.The core component adopts the 16-bit microcontroller, whose powerful function and high speed arithmetic capability guarantee the excellent quality of the transmitter.The entire design framework focuses on reliability, stability, high accuracy and intelligentization to meet the increasing requirements of industrial field application.For this reason, digital signal processing technology is applied in the software, so that it has excellent anti-interference ability and zero stability, as well as zero automatic stability tracking ability (ZSC) and temperature automatic compensation ability (TSC).

• The use of microprocessor increases the flexibility and function of intelligent transmitter.

• Intelligent electronic components are composed of only one board, which has more advantages and higher reliability.

• Range ratio 10:1 or 100:1.

• Range width: 0-25pa ~42MPa.

• Press the button to adjust the zero and range.

• The existing 3051/1151 analog transmitter can be updated to intelligent transmitter.

• In accordance with the HART agreement, the HART communicator can be used to communicate with the table in two-way communication without interrupting the output signal.

• With self-diagnosis and remote diagnosis function.

• Data with EEPROM, is not afraid of power loss.
