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 transmitter cable has a diameter of Ø 8 mm and also contains a vent pipe for connection to atmosphere.
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.

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 P320/420

The first pressure transmitter with remote safety handling

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 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.

The devices are suited for applications where safety is critical: in industries such as chemical, oil and gas, and power generation.

Besides that both pressure transmitters have an increased proof test interval over other devices on the market, significantly lowering maintenance costs with testing periods of up to fifteen years rather than every two.

The reduced response time of the devices optimizes the process efficiency by speeding up the control system’s response to changing application environments.

SITRANS P320/420’s user-friendly features also include a new larger and improved HMI display, showing users the device’s status at a glance. The setup is convenient and quick thanks to four-button programming, NAMUR NE107 support and a quick start wizard.
