Note: The measuring range, output type, process connection, electrical connection, Ex option and other technical parameters may vary according to the selected MLFB. Therefore, instead of ordering based only on the “SITRANS P220” model name, the complete MLFB and technical configuration should be verified.
The SITRANS P220 provides a wide range of gauge pressure measurement options.
Examples of measuring ranges specified in Siemens technical documentation include:
0–2.5 bar
0–4 bar
0–6 bar
0–10 bar
0–16 bar
0–25 bar
0–40 bar
0–60 bar
0–100 bar
0–160 bar
0–250 bar
0–400 bar
0–600 bar
0–1,000 bar
For example, for the 0–600 bar measuring range, Siemens documentation specifies an overload limit of 1,500 bar and a burst pressure of 2,500 bar. For the 0–1,000 bar version, the overload limit is also 1,500 bar and the burst pressure is 2,500 bar.
Therefore, describing the P220 only as a transmitter “up to 600 bar” does not fully represent its current technical range; options up to 1,000 bar are particularly important for high-pressure applications.
One of the important application areas of the SITRANS P220 is refrigeration technology.
Siemens specifically positions the P220 for high-pressure and refrigerant applications. Therefore, the transmitter can be considered for systems such as:
Chiller systems
HVAC equipment
Refrigeration circuits
Compressor systems
Refrigerant lines
High-pressure refrigeration applications
However, in an application involving refrigerants, a suitable pressure range alone is not sufficient. Compatibility of the wetted materials with the process medium, process temperature, pressure level and selected P220 configuration should be evaluated together.
The P220 measuring cell features a piezoresistive design with a stainless-steel diaphragm.
According to Siemens documentation, the materials of components in contact with the process medium include:
Measuring cell: 1.4016 stainless steel
Process connection: 1.4404 / 316L stainless steel
The housing is also specified as 1.4404 / 316L stainless steel.
Therefore, particularly in refrigerant, gas or chemical applications, material compatibility should be verified based on the complete MLFB.
The P220 can provide different output options depending on the selected version.
The 4–20 mA output is a widely used analog signal in industrial automation and control systems.
The 4–20 mA versions of the P220 can be used with a two-wire connection.
Suitable P220 configurations can also provide a 0–10 V DC voltage output.
Therefore, when replacing or sourcing a P220, it is important to check the analog input type of the existing control system.
The degree of protection of the P220 depends on the electrical connection.
According to Siemens documentation:
Versions with EN 175301-803-A connector: IP65
Versions with M12 connector: IP67
Cable versions: IP67
Versions with screwed cable connection: IP67
Therefore, instead of specifying a single IP rating for the entire product family, it is more accurate to state IP65 or IP67 depending on the selected electrical connection.

Before commissioning the P220, the following parameters should be checked:
Complete MLFB and product configuration
Measuring range
Gauge pressure measurement type
Process connection
Electrical connection
Output type
Process medium and material compatibility
Process temperature
Ambient temperature
Ex certification, if required
When making the electrical connection, the supply voltage and loop requirements of the selected version should be verified.
For 4–20 mA versions, Siemens documentation specifies an auxiliary power supply range of DC 7–33 V; the applicable limits for Ex versions should also be taken into account.

The complete MLFB is critical for correct product sourcing in P220 projects.
The SITRANS P220 product family is included under the 7MF1567 product-number family. However, 7MF1567 alone does not define the complete product configuration.
For example, Siemens product records include complete MLFBs such as:
7MF1567-3CD00-1AA1
In this example, the product is defined with a specific 4–20 mA, two-wire configuration, measuring range and electrical/process connection options. Therefore, this example MLFB should not be copied directly for another application.
During a replacement or new sourcing process, the following information should be checked together:
Complete Siemens MLFB
Measuring range
Output type
Process connection
Electrical connection
Wetted-part materials
Process temperature
Process medium / refrigerant
Ex requirements
Mechanical dimensions
Application conditions
When an existing P220 needs to be replaced, selecting a new product based only on the “P220” model name is not the correct approach.
Especially in high-pressure and refrigerant applications, the following parameters should be compared:
Original MLFB → Measuring range → Output → Process connection → Material → Electrical connection → Temperature → Ex requirements → Application
Another Siemens pressure transmitter with a similar measuring range should not automatically be assumed to be a direct one-to-one replacement.
A technical suitability check and cross-reference analysis should be performed before ordering.
The Siemens SITRANS P220 is a compact, single-range gauge pressure transmitter designed particularly for high-pressure and refrigeration applications.
According to Siemens technical documentation, the P220 is available with gauge pressure measuring ranges up to 1,000 bar.
The measurement deviation is typically 0.25%, with a maximum of 0.5%. The actual value should be evaluated according to operating conditions and the selected configuration.
Depending on the configuration, 4–20 mA or 0–10 V DC output options are available.
Yes. The P220 is positioned by Siemens for high-pressure and refrigerant / refrigeration applications. However, compatibility between the refrigerant and wetted materials, as well as the process conditions, should be verified separately.
Depending on the electrical connection, the protection rating can be IP65 or IP67. M12 and cable versions provide IP67 options, while the EN 175301-803-A connector version is IP65.
The first step is to verify the complete MLFB of the existing device. The measuring range, output type, process connection, materials, temperature, electrical connection and Ex requirements should then be compared.
