Pressure measurement
Pressure on you to produce quickly, safely and efficiently. Not to mention the actual pressure in your process – which you need to measure with maximum precision at all times. Tailored to the specific requirements of your applications, Siemens pressure measurement devices provide the confidence you need in your instrumentation – helping to relieve some of that pressure.
Pressure Measurement
SITRANS P320/420
SITRANS P320/420 are 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.

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.
Detail
Accuracy ≤ 0,075 %
Long term stability ≤ 0.25 % / 60 months
Measuring range 0 – 10 mbar (0 – 4 inchH2O) to
0 – 400 bar (0 – 5800 psi)
Communication HART or PROFIBUS PA
SITRANS P200/P210/P220
SITRANS P200, P210 and P220 are compact single-range transmitters for measuring absolute and gauge pressure. These series use two types of pressure sensors: two stainless steel sensors and one ceramic diaphragm sensor. This makes it easy to measure process, absolute and hydrostatic pressure. The determined pressure is optionally converted into a 4-20 mA or 0-10 V signal.
Detail
Nonlinearity ≤ 0,25 %
Long-term stability ≤ 0,25% / 12 Monate
Measuring range SITRANS P200: 1 bar to 60 bar gauge
0,6 bar to 16 bar absolute
SITRANS P210: 100 mbar to 600 mbar gauge
SITRANS P220: 2,5 bar to 1000 bar gauge
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.
Detail
Accuracy ≤ 0,2 %
Long-Term Stability ≤ 0.1 % / 12 months
Measuring range 0 – 160 mbar (0 – 64 inchH2O) to
0 – 40 bar (0 – 580 psi)
Certificates/ Approvals ATEX
SITRANS LH100
The pressure transmitter SITRANS LH100 is a well probe and converts the level-proportional hydrostatic pressure into a standard signal of 4 – 20 mA. It measures levels in basins, containers, canals and dams. It has a stainless steel housing and a piezoresistive sensor with a ceramic membrane and is available for a wide range of measuring ranges and, if required, with explosion-protection.
