Pressure transmitter

Accuracy in changing environments

Validyne’s (US) P66 is a digital differential pressure transmitter designed for industrial pressure measurement applications. An on-board microprocessor provides accuracy and stability in changing thermal environments.

A CAN INERFACE ENABLES DIGITAL OPERATION with a PC. Communication via CAN offers remote zero and span adjustment as well as digital pressure readings in engineering units or pressure counts. The zero and full-scale outputs are set by CAN digital command. No potentiometer adjustments are required to calibrate. Pressure readings via the CAN port are available in engineering units. The temperature reading at the sensor is also available via CAN. An analog output of ±5 VDC is also available. A free CAN utility is available to get readings from the transmitter as well as to perform auto zero and auto span operations. The product is powered by +5 to +55 VDC and draws just 5 mA. It is suitable for automotive pressure measurement, level measurements, engine test cells, and test track pressure measurements. The transmitter has 1/8-inch socket NPT pressure connections and measures 3,81 cm x 3,81 cm x 12,7 cm.
The transmitter is designed for a variety of low-pressure measurements where resistance to vibration and stability through temperature changes is required. It will accept both liquids and gases directly at the sensing diaphragm. The transmitter provides digital readings directly in engineering units of psi or inches of water column. It offers 0,25 % full-scale accuracy and 0,7 % maximum temperature error.
