A diaphragm-type transmitter is a pressure measurement device that uses a thin, flexible membrane (the diaphragm) as the primary sensing element. It is the industry standard for measuring pressure, differential pressure, level, and flow in demanding process conditions.
| Isolation | Keeps the process fluid away from the delicate sensor electronics. |
| Hygienic Design | "Flush" diaphragms have no crevices, making them ideal for food, beverage, and pharma (CIP/SIP). |
| High Accuracy | Capable of detecting very small changes in pressure (0.05% accuracy or better). |
| Overpressure Protection | Many designs allow the diaphragm to "bottom out" against a backup plate to prevent rupture during pressure spikes. |
