Series 644 High Accuracy Pressure Transmitter
Does not ship to VA, United States
Description
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.
Features- High accuracy provides exceptional measurement for insuring tight-control and minimizing costly out of specification conditions
- NIST calibrated to provide traceability for regulated processes where production and documentation is monitored
- Low thermal error over a wide range of temperatures helps to insure accurate pressure measurement and process operation
