Siemens Sitrans P320 & P420 7mf0300 Liquid Level Gauge
Product Description
Siemens SITRANS P320 Smart Pressure Transmitters 
Siemens SITRANS P320 is a SIL-rated smart pressure transmitter specifically designed for applications where safety is critical: in industries such as chemical, oil and gas, and power generation. It can be used in industrial areas with extreme chemical and mechanical loads
The Siemens SITRANS P320 & P420 Pressure Transmitter is a precision digital transmitter for pressure, absolute pressure, differential pressure, flow and level and has extensive diagnostics and simulation functions. The Siemens SITRANS P320 / P420  has remote safety handling via SIMATIC PDM saving you time during commissioning.
Rather than having to manually attend each individual device across a facility, operators can program transmitters from the control room. This reduces the commissioning time in applications requiring functional safety. Both SITRANS P320 and P420 pressure transmitters have an increased proof test interval over other devices on the market.
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

Siemens SITRANS P320 is a SIL-rated smart pressure transmitter specifically designed for applications where safety is critical: in industries such as chemical, oil and gas, and power generation. It can be used in industrial areas with extreme chemical and mechanical loads
It features an increased proof test interval (up to 15 years) over other available devices on the market, significantly lowering maintenance costs. Its fast response time optimizes the process efficiency by speeding up the control system's response to changing application environments.
The SITRANS P320 can be ordered with a large integral HMI display that shows the device's status at a glance. A display cover with a window lets you see the HMI without opening the transmitter case. Setup is convenient and quick through standard four-button programming. Support for NAMUR NE107 diagnostics and a quick start wizard are included.
SITRANS P320 transmitters are designed to replace older Siemens SITRANS P DS-III series transmitter models

Four pushbuttons under nameplate cover for configuration changes to the device; Integrated Quick Start wizard and parameter assignment using HART protocol and SIMATIC PDM
Display includes process variable in your choice of engineering units, including % or mA, and a 12-character free text message; Symbols on display show NAMUR device failure or out-of-specification, maintenance alerts, function test, output signal failure, and event counters
Display can rotate 360° for optimal viewing
