SITRANS FS230 digital clamp-on ultrasonic flow system includes the SITRANS FST030 transmitter and proven-in-use FSS200 sensors. These sensors are ideal for typical applications or for challenging hazardous areas the external electronics module SITRANS FS DSL may be used. The FS230 provides rugged and industry-leading performance with cost savings in both purchasing and operation. It works as a non-intrusive interface detector and is capable of measuring flow in petrochemical applications requiring differentiation between changing liquids in a pipeline as well as determination of liquid quality. The FS230 clamp-on flow meter is ideal for industries requiring high-quality liquid flow measurement, such as hydrocarbon, chemical, water and wastewater, HVAC, power, food and beverage, pharmaceutical, mining, and pulp and paper.

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 thanks to extended calibration intervals, and ensures a high reliability on the measured results long term.


SITRANS P320/420

SITRANS P320/420 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 programming each individual device across a facility, operators can access transmitters from the control room. This reduces the commissioning time in applications requiring functional safety. 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. This lowers maintenance costs significantly.



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. 



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. 



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

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.



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.



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.



The SITRANS LH300 pressure transmitter 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. This versatile transmitter consists of a stainless steel housing with IP68 mechanical protection and a piezo-resistive sensor with 99.6% pure ceramic diaphragm. It is also ideal for use in drinking water systems.

When connected directly in the 4 to 20 mA loop, the SITRANS TR devices require no auxiliary power supply. They are installed in junction boxes or in the control room close to the process, thus permitting centralized access to all connected measurement points.


The field transmitter for rugged industrial environments.

Because of its IP67 protection, SITRANS TF is used in environments too tough for other transmitters.

It measures signals from resistance thermometers, resistance-type sensors, thermocouples and voltage sensors, and converts the signal into direct current signal (HART) or bus signal (Profibus PA, Foundation Fieldbus or Wireless HART) in accordance with the sensor characteristics


The SITRANS TO500 multipoint measuring system is used for evaluating a large number of temperature measuring sensors arranged on a very narrow fiber-optic temperature measuring lance.


SITRANS TS-Temperature Sensors are the perfect basis for precise and safe temperature measurement. The RTDs and Thermocouples support a broad range of application through the process industries.

  • Model 61H High-Capacity Booster Relay is designed to improve the stroking speed of large diaphragm valves

  • Model 61VH High-Capacity Booster Relay is designed for use on control valve actuators that require very fast stroking speeds


Air Filters and Accessories

Filter Regulators, Integral Volume Booster and Venting Gauge Block- The Model 91-HF Filter-Regulator is designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment.  The Model 2306 instrument air filter is used to remove dirt, oil, water, and other impurities from an instrument-air supply. The Integral Volume Booster was designed for use on pneumatic actuators that require high flow for fast stroking times.  The unit reproduces pneumatic signals in a 1:1 ratio for applications requiring increased flow capacity, while maintaining small step accuracy and reducing piping requirements. 

When a Double Acting SIPART PS2 is used with a Single Acting actuator, the following must be considered:

With loss of supply air the Double Acting SIPART PS2 will lock in the last position. This prevents the actuator spring from returning the valve to its fail-safe position. By using the "venting" gauge block and properly piping the positioner to the actuator the air on the side opposite the spring can be exhausted back through the air supply line.
