LTC diaphragm in diaphragm seal technology

Contents

The LTC diaphragm (LTC = Low Temperature Coefficient), developed in-house by Labom, compensates for temperature-induced volume expansion of the pressure-transmitting fluid using a stainless steel diaphragm. The mechanically robust stainless steel diaphragm, with a thickness of at least 0.1 mm, is positioned between two zero points via a special manufacturing process in such a way that it operates with virtually no residual force. As a result, the diaphragm absorbs volume changes in the fluid caused by temperature with virtually no feedback. Compared to conventional sinusoidal diaphragms, an LTC diaphragm can deliver up to 70 per cent higher measurement accuracy.
