Speed Pick-up
SU63
The Validyne SU63 is an AC inductive speed pick-up used for RPM measurement on high-speed rotating equipment. The SU63 is a tightly-wound coil with a laminated core that can be conveniently mounted on rotating equipment so that the magnetic field of a magnetized nut or part passes through the coil windings. The moving magnetic field produces a voltage within the coil proportional to its rate of change and the strength of the permanent magnetized part. The frequency of this inductive voltage spike is fed into an oscilloscope or counter to determine RPM.

Network Sensor Interface for USB Pressure Transducers
SI314
The Validyne model SI314 is a network interface that connects our model P61 USB pressure Transducer to your smart phone or network web browser. The SI314 supports Ethernet and Wi-Fi connections and will display current pressure readings and transducer status on any web browser or via smart phone. The SI314 also displays the transducer temperature, date of calibration, model and serial numbers and these can be viewed wirelessly or by Ethernet connection. The SI314 makes your P61 accessible from anywhere in the world. Data logging of pressure data is configured via a web browser or smart phone and readings may be stored once per minute to once per hour. A thumb drive or memory card collects the data in comma separated file format(csv) for download to your computer. The data may also be accessed via the network. A graph of the data is also generated on request. A Twitter function allows pressure data to be tweeted from the SI314 at user-defined intervals. The transducer zero and span calibration adjustments are password protected and operated via browser buttons. No potentiometer adjustments are required to calibrate the P61 transducer.

Very Low Pressure Variable Reluctance Sensor
DP103
The Validyne DP103 is designed for exceedingly low differential pressure measurement applications where high accuracy is required under rough physical conditions. With full scale ranges down to -0.008 psid (-0.56cm H2O), this instrument is being used in the measurement of very low flow rates of gases where symmetrical pressure cavities are required for dynamic response. It is also used in very small leak detection and pressure null detection systems.

Single-Channel DC Powered Carrier Demodulator
CD16
The CD16 Miniature Carrier Demodulator is designed to deliver a 0 to 5 Vdc output from a variable reluctance transducer and operate from unregulated 9 to 55 Vdc power. A square wave excitation of 5 kHz is furnished to the transducer and the solid state integrated circuit amplifier and demodulator converts the transducer signal to an analog dc output. Zero and Span adjustments are made through access holes in the case.
