The SITRANS P Compact pressure industrial transmitter is designed for the special requirements of the food, pharmaceutical and biotechnology industries. The use of high-grade materials guarantees compliance with hygiene regulations. The SITRANS P Compact pressure transmitter is available in many versions. Exact adaptation of the pressure transmitter to conditions at the place of use is thus possible ■ Design The electronics is potted to protect it against moisture, corrosive atmospheres and vibration. Notes on operating the pressure transmitter Compensation of internal atmospheric pressure • in the plug versions by means of the screwed gland (IP65) • in the field housings by means of an integral sintered filter (IP65) or a vented cable (IP67) • in versions with cable outlet by means of a vented cable (IP67) In the absolute pressure range there is no need for compensation with respect to atmospheric pressure. Note: These degrees of protection are only achieved under the following conditions: • if the pressure transmitter is installed correctly • if the screwed glands are securely tightened • if the cable diameters agree with the nominal diameters of the gaskets in the housing Note: The integral EMC measures are only effective if the earth connection is made correctly. CE marking The CE marking of the pressure transmitter certifies compliance with the guidelines of the European Council (9/336/EC), the EMC law (13.11.1992), as well as the applicable generic standards. Interference-free operation in systems and plants is achieved only if the specifications for industrial shielding, earthing, cable routing and electrical isolation are observed during installation and assembly. Hazardous areas Note: Electrical equipment in hazardous areas must only be installed and operated by trained personnel. Modifications to units and connections result in cancellation of the explosion protection and guarantee. With intrinsically-safe circuits, make sure that equipotential bonding exists throughout the complete cabling inside and outside of the hazardous area. The limits specified in the ATEX approval must be observed. |
