Diaphragm Seal Type Pressure Gauge P710, P720, P730
Brand: Wise Control IncDiaphragm seal type gauges are suitable for the situation where the process medium would corrode the instrument connection and pressure sensing element.
Furthermore, this type of gauge is highly recommended in a situation where the process medium contains suspended solids, or if it is sufficiently viscous to clog the instrument connection and pressure sensing element.
Additionally, it is recommended to be used where the process medium might freeze or solidify the instrument connection and pressure sending element due to the ambient or process temperature change, and where the process medium requires the flushing from the system to prevent any contamination.
