Pressure Measurement

SITRANS P pressure transmitters are a complete family of measuring instruments for measuring gauge, differential, and absolute pressure that includes a range of performance values, load capacities, and materials. In addition to high measuring accuracy and ruggedness, the modular system features superb operating convenience and functionality as well as an ideal safety concept. Whether it’s international approvals or industry standards, our transmitters meet the challenges presented by increasingly complex tasks in the process industries.

Sitrans P500

The SITRANS P500 is a digital pressure transmitter for the measurement of differential pressure, level and flow with highest accuracy. It guarantees a characteristic curve deviation of ≤ 0.03 % as well as outstanding values for the influence of static pressure and temperature on the measured result. The high long-term stability of the sensor reduces maintenance costs due to extended calibration intervals, and ensures a high reliability on the measured results long term.

SITRANS P320/420, pressure measurement

SITRANS P420

SITRANS P420 is the first pressure transmitter on the market to feature 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. What´s more both pressure transmitters have an increased proof test interval over other devices on the market. With testing periods of up to fifteen years rather than every two they are lowering maintenance costs significantly.

SITRANS P320

SITRANS P320 is the first pressure transmitter on the market to feature remote safety handling. The instruments’ remote safety handling via SIMATIC PDM saves time during SIL commissioning: 

  • Benefits
    Reduced commissioning time due to remote safety handling
  • Suitable for harsh conditions due to robust materials
  • User-friendly due to clear and large display and diagnostic icons acc. to NAMUR NE107 and a quick start wizard
  • Maintenance cost reduction due to proof test interval up to 15 years
  • Fast reaction and optimized processes due to reduced response time 
SITRANS P410, pressure measurement

SITRANS P410

The SITRANS P410 is a digital pressure transmitter with integrated diagnostic functions. It complements the existing P DS III as a “high performance” version with increased measuring accuracy of 0.04 % and offers different design variants for measuring gauge and differential pressure.

SITRANS P DS III, pressure measurement

SITRANS P DS III

The SITRANS P DS III series includes digital pressure transmitters for measuring gauge pressure, absolute pressure, differential pressure, flow and level. Even the standard devices offer comprehensive diagnostics and simulation functions with high reliability. 

SITRANS P310, pressure measurement

SITRANS P310

The SITRANS P310 is a digital pressure transmitter with integrated HART diagnostic functions and a high operating comfort. Representing a basic device for easy measurements with low accuracy requirements the P310 complements the already existing P DS III. The different design variants for measuring gauge and differential pressure are available. 

SITRANS P300, pressure measurement

SITRANS P300

The SITRANS P300 offers measuring precision and ruggedness. Its stainless steel housing with laser-printed nameplate, together with a wide range of hygienic process connections, mean that it is highly suitable for use in the food & beverages industry as well as for pharmaceutical processes. 

SITRANS P280, pressure measurement

SITRANS P280

The SITRANS P280 is a WirelessHART pressure transmitter that provides all measured process values as well as diagnostic information, parameters and functions via radio. The device is powered by an internal battery and designed for ultralow power consumption. The compact and rugged design makes it especially suitable for direct mounting on tanks and pipes in remote parts of plants, and on moving or rotating equipment for process monitoring or asset management applications.

SITRANS P200/P210/P220, pressure measurement

SITRANS P200-P210-P220

The SITRANS transmitters P200, P210 and P220 are compact single-range-transmitters for measurement of absolute and gauge pressure. In this series we use two different kinds of pressure sensors: two stainless steel sensors and one ceramics sensor. So the measurement of process pressure, absolute pressure and hydrostatic pressure is an easy thing. The measured pressure will be transformed with these sensors into a 4…20-mA- resp. a 0…10-V-signal.

SITRANS P Compact, pressure measurement

SITRANS P Compact

The SITRANS P Compact is an analog transmitter for measuring absolute and relative pressure which has been developed specially for the requirements of the food/pharmaceutical and biotechnology industries.

SITRANS LH100, pressure measurement

SITRANS LH100

The SITRANS LH100 series pressure transmitter is a well probe and converts the level-proportional hydrostatic pressure into a standardized signal of 4 to 20 mA. It measures the level in basins, tanks, canals and dams. The SITRANS LH100 is available for different measuring ranges and optionally with explosion protection. The transmitter has a stainless steel housing and a piezoresistive sensor with a ceramic diaphragm.

SITRANS LH300, pressure measurement

SITRANS LH300

The pressure transmitter SITRANS LH300 is a submersible sensor for hydrostatic level measurement with protective caps made of PPE, stainless steel and ETFE. The transmitter converts the level-proportional hydrostatic pressure into a standardized 4 to 20 mA signal. The transmitter consists of a stainless steel housing (Ø 30 mm) with mechanical protection IP68 and the piezo-resistive sensor with ceramic diaphragm made of 99,6 % purity ceramic ensures versatile use, also good in drinking water systems. The pressure transmitter measures liquid levels in tanks, containers, channels and dams. SITRANS LH300 pressure transmitters are available for various measuring ranges and with explosion protection as an option.
