Pressure Measurement

TIA is constantly improved and expanded - future-proof automation for your production. Totally Integrated Automation from Siemens – The worlds leading automation concept. Holistic approach. End-to-end consistency. Innovative & future-proof. Maximum connectivity.

We are deal in a SIEMENS Smart pressure transmittier this products are use in process industry . 

SITRANS P420 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.

Applications

Application range Overview Depending on the version, a transmitter measures corrosive, non-corrosive and hazardous gases, vapors and liquids. You can use the transmitter for the following types of measurement: ● Gauge pressure ● Absolute pressure ● Differential pressure With appropriate parameter settings and the necessary add-on parts (e.g. flow orifices and remote seals), the pressure transmitter can also be used for the following measurements: ● Level ● Volume ● Mass ● Volumetric flow ● Mass flow rate The output signal is always a load-independent direct current between 4 and 20 mA. You can install the "intrinsically-safe" or "explosion-proof" version of the transmitter in hazardous areas. The devices have an EC type examination certificate and comply with the appropriate harmonized European CENELEC directives. Transmitters with remote seals of different shapes can be delivered for special applications. For example, measuring high-viscosity substances is a special application. Gauge pressure This version measures aggressive, non-aggressive and hazardous gases, vapors and liquids. The smallest span is 0.01 bar g (0.145 psi g), and the largest 700 bar g (10153 psi g). Differential pressure and flow rate This version measures corrosive, non-corrosive and hazardous gases, vapors and liquids. You can use this version for the following measurement types: ● differential pressure, e.g. effective differential pressure ● Gauge pressure, suitable for small positive or negative pressure value ● in combination with a restrictor device: flow rate q ~ The smallest measuring span is 1 mbar (0.0145 psi), the largest 30 bar (435 psi)
