| Accu-Seal Diaphragm Seal |
System modified to extend the pressure sensor into the process media, thus eliminating any deadleg in the system. Due to the sensor proximity to the threads, some of the stress on the threads during installation can get transferred into the sensor and therefore show up as a zero shift on the display. These shifts are typically small, but should be zeroed out after the unit is installed.
Note: Requires 4-1/2 inch size with 1/2 inch NPT connection. Available with ranges to a maximum pressure 2000 psig
