Pressure Transmitter Suits High-Accuracy Applications

Dwyer Instruments' Series 644 industrial pressure transmitter features a design suitable for high-accuracy pressure applications. The Series 644 offers accuracy of ±0.05% FS RSS (<±0.25% TEB). The transmitter 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 10 psig pressure ranges (optional 0 to 15 psia). The robust and compact all stainless-steel Series 644 is available with either a ¼-inch male NPT, or 7/16-inch 20 male SAE process connections. Each transmitter is provided with an 11 point NIST traceable calibration certificate.
