While the KELLER 23-Ed Series Flameproof Pressure Transmitter is designed to be -free, the optimal recalibration frequency is dependent on your specific application and operating conditions. For most users, the manufacturer recommends recalibrating the transmitter every year. This ensures continued accuracy and reliable performance, especially crucial in hazardous environments where this pressure transmitter is often used. Regular recalibration helps to maintain the precision of pressure readings, supporting safe and efficient operations.
