±0.05% FS, <±0.25% FS Total Error Band
The SERIES 644 Industrial Pressure Transmitter is a robust transmitter designed for high accuracy pressure applications. Boasting an accuracy of ±0.05% FS RSS (<±0.25% TEB), the 644 is intended for precise measurements in the critical applications of calibration technology, hydraulic/pneumatic controls, and many more laboratory and industrial settings. The Series 644 offers multiple measurement options with two output choices (VDC or mA) and ten psig pressure ranges (optional 0 to 15 psia). The robust and compact all stainless steel Series 644 is available with either a 1/4" male NPT, or 7/16"-20 male SAE process connections. Each transmitter is provided with an 11 point NIST traceable calibration certificate.
