Depending on the selected ordering code the following models are available:a) Model 266 DRH which allows a Differential measurement using either two remote seals of same type and size or one remote seal (on positive or negative side) and a standard threaded connection direct 1/4 18 NPT on flange or 1/2 14 NPT through adapter, for the wet or dry leg on the side opposite to ) models 266 PRH or 266 VRH allowing gauge or absolute measurement respetively with the reference side at atmosphere or at vacuum .

4 The other side which can be the positive or negative (high or low pressure side) features the required remote 266HR or 266NR have the remote seal on the positive side and the user can select the suitable code for having the reference at armospheric or vacuum pressure respectively for gauge or absolute measure. The following table list the types of standard seal which can be combined with 266xR transmitters. Refer to seal data Sheet for all data and details relevant to seal element.
