Kromschroeder DG18I-3 (84447050) Gas-Vakuum-Sensor

Kromschroder DG18I-3 84447050 gas pressure switch designed for monitoring increasing and decreasing gas or air pressure. Maintenance In order to ensure smooth operation: Check the tightness and function of Kromschroeder DG18I-3 84447050 differential pressure switch every year, or every six months if operated with biogas. A function check can be carried out in case of decreasing pressure control e.g. with the PIA. After carrying out the maintenance work, check for tightness. Technical data Adjusting range: -2 – -18 mbar Gas type: natural gas, town gas, LPG (gaseous), flue gas, biogas (max. 0.1 %-by-vol. H2S) and air Negative pressure for gas Electrical connection via screw terminals and M16 cable gland, IP 54 Maximum medium and ambient temperatures: -20 to +80°C Storage temperature: -20 to +40°C Long-term use in the upper ambient temperature range accelerates the ageing of the elastomer materials and reduces the service life Diaphragm pressure switch, silicone-free Diaphragm: NBR Housing: glass fibre reinforced PBT plastic with low gas release Lower housing section: AlSi 12 Enclosure: IP 54 or IP 65 Safety class: 1 Line diameter: 0.5 to 1.8 mm (AWG 24 to AWG 13) Line entrance: M16 x 1.5, clamping range: diameters of 4 to 10 mm Type of connection: screw terminals Weight: 0,321 kg Designed lifetime This information on the designed lifetime is based on using Krom schroder 84447050 DG18I-3 pressure switch in accordance with these operating instructions. Once the designed lifetime has been reached, safety-relevant products must be replaced. Designed lifetime (based on date of manufacture) in accordance with EN 13611, EN 1854 for Kromschroeder 84447050 DG18I-3 gas pressure switch.
