This temperature sender can be used to measure water (vaporiser) or gas (rail) temperature for a Bigas, or any other AEB-based, gas injection system. For gas, it is fitted in the gas line either between a pair of rails or between vaporiser and rail. For water, it is fitted near the outlet from the vaporiser. The pipe has a 16mm diameter, with a retaining lip. The sender resistance varies from about 10k Ohms when cold to 1k when hot.
