Pressure Pressure transducer for measuring the temperature of refrigerants FDA 602 LxAK • Compact pressure sensors for industrial applications in liquid and gaseous substances. • Piezo-resistive, flexibly suspended silicone measuring cell in an oil-filled, all-welded special steel enclosure. • The stable mechanical construction provides a reliable protection for the measuring cell against the test substance and immunes it against pressure peaks and vibrations. • Absolute pressure: pressure related to vacuum (0 bar). Technical Data: Overload Two times final value Output signal Total error range 0 to +50 °C ±1.0 % of final value -10 to +80 °C ±1.5 % of final value (linearity + hysteresis + reproducibility + temperature coefficients + zero-point + range tolerance) Response time (0 to 99 %) Nominal conditions Power supply 6.5 to 15 VDC, consumption <4 mA via ALMEMO® connector Operating temperature Pressure terminal male thread 7/16“ membrane not flush with front Material in contact with medium Stainless steel DIN 1.4404/1.1135 External seal, Viton Weight Protective class Calculation of the refrigerant temperature with device special version SB0000R2 (LINEARIZATIONS FOR OTHER REFRIGERANTS ON REQUEST) 11/2025 • We reserve the right to make technical changes. The ALMEMO® Version V6 devices, (2590-2/-3S/-4S, 2690, 2890, 8590, 8690, 5690) can be used for continuous temperature measurement (resolution 0.1 K) with absolute pressure sensors (resolution 0.001 bar compulsory!). Both, pressure and temperature can be selected or continuously indicated and recorded. Technical data for ALMEMO® option SB0000R2: Refrigerant: R22 R23 R134a R404a R404a Pressure Range: Temperature Range: Operation point: Pressure Range: Temperature Range: Operating point: *) The final temperature is obtained from the data of the refrigerant. For pressure transducer with smaller pressure ranges, the specified final temperature changes. (Linearizations for other refrigerants on request) Special design refrigerant temperature for ALMEMO® devices V6 (Please order when buying new devices or send it to upgrade existing device) including ALMEMO® connecting cable, 1.5 m, and programming of a refrigerant measuring channel Measuring ranges Absolute pressure (resolution 0.001 bar) up to 10 bar up to 30 bar up to 50 bar Measuring range up to 100 bar and up to 150 bar on request DAkkS accredited calibration or factory calibration KD9xxx pressure for sensor or measuring chain (sensor + device), see chapter „Calibration certificates“.
