SITRANS P320 is the first pressure transmitters with remote safety handling: It enables the user to program all devices from the control room instead of each individual transmitter on site. This shortens commissioning, especially in applications that require functional safety. A test period of up to 15 years instead of the usual 2 years ensures low maintenance costs.

Description

Siemens SITRANS P320 Pressure Transmitter

SITRANS P320 is the first pressure transmitters with remote safety handling. The instruments’ remote safety handling via SIMATIC PDM saves time during SIL commissioning: rather than manually attending to each individual device across a facility, operators can program transmitters from the control room. This reduces the commissioning time in applications requiring functional safety.

Overview---SITRANS P320

SITRANS P320 pressure transmitters is digital pressure transmitters featuring extensive user-friendliness and high accuracy. The parameter assignment is performed using input buttons or the HART interface.

The comprehensive functionality makes for precise adjustment of the pressure transmitter to the requirements of the plant. Operation is very user-friendly in spite of the numerous setting options.

Due to their advanced diagnostic functionalities according to NAMUR NE107, the SITRANS P320 pressure transmitters are very suitable for use in chemical plants. Thanks to the advanced diagnostic functions and the process value storage, the SITRANS P420 is "Ready for Digitalization".

The "Remote Safety Handling" function saves customers significant amounts of time and money, because the SIL function can be switched on and validated remotely via SIMATIC PDM. This eliminates travel times and on-site operation via the local display or keyboard.

Parameter assignment using the HART protocol is very easy and quick thanks to the innovative EDD with integrated Quick Start wizard.

The transmitters can be equipped with various types of remote seals for special applications such as the measurement of highly viscous substances.

SITRANS P320 pressure transmitters are available in various versions for measuring:

  • Gauge pressure
  • Absolute pressure
  • Differential pressure
  • Level
  • Volume flow
  • Mass flow

  • Infinitely adjustable spans from 0.01 bar to 700 bar (0.15 psi to 10153 psi)
  • Convenient parameterization over 4 input buttons and HART interface

Application

SITRANS P320 pressure transmitters can be used in industrial areas with extreme chemical and mechanical loads.

The pressure transmitters can be used in zone 1 or zone 0 with the corresponding Ex approval.

It can be equipped with various designs of remote seals for special applications such as the measurement of highly viscous substances.

The pressure transmitter can be operated locally over 4 input buttons or programmed externally over HART interface.
