Transmitter Type 2100 & 2500

These on-off Type 2100 pneumatic switches sense high or low liquid levels. These switches pneumatically operate safety shutdown systems for field processing equipment in oil and gas production applications. Sour gas service capability: (NACE) MR0175. Type 2500 pneumatic level transmitter uses the 249 Series displacer-type Level-Trol® sensors. The displacer sensor measures changes in liquid level, specific gravity or interface level, and the instrument transmits a pneumatic signal that is proportional to the changes. The displacer is contained in a rugged cage for mounting on the side of a tank, or the displacer can be suspended in a tank without a cage
