Description
Gems 5266 low range pressure transmitter measures gauge or differential pressure by means of a stainless steel diaphragm, and capacitive sensor. The model 5266 incorporates an ASIC to provide a temperature compensated high level analogue out put over the temperature range -18 to +65°C. Mounted in a glass filled polyester case with pipe fittings the 5266 can measure pressures in the range 100 - 5000 pascals. The 5266 utilises an all stainless steel microtig welded sensor. The tensioned stainless steel diaphragm and insulated stainless steel electrode, positioned close the diaphragm, form a variable capacitor. Positive pressure moves the diaphragm toward the electrode, increasing the capacitance. A decrease in pressure moves the diaphragm away from the electrode, decreasing the capacitance. The change in capacitance is detected and converted to a linear DC electrical signal by Gems’ unique electronic circuit. The micro-tig welded tension sensor allows up to 69kPa overpressure (in either direction) with no damage to the unit. In addition, the sensor parts have thermally matched coefficients, which promote improved temperature performance and excellent long-term stability
