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.

Pressure Sensor Interface
USB2251
The USB2251 Pressure Sensor Interface provides real-world data acquisition for your PC via the USB port. 8 calibrated variable reluctance pressure sensor inputs are accepted by the USB2251. No external signal conditioning is required.The USB2251 includes a connector panel for sensor cables, calibration constants for each sensor , configuration and data acquisition software. The USB2251 produces a floating-point value for all readings, directly in engineering units.The USB2251 can record pressure readings up to 5000 samples per second. Combined with the fast response of the Validyne VR pressure sensors, the USB2251 is ideal for transient pressure studies. The USB2251 is compatible with the following Validyne variable reluctance pressure sensors: AP10, DP103, DP10, DP45, DP15 DP360, DP215, and DP363. Each sensor is calibrated with the USB2251 at the factory and is ready to make measurements.

Portable Digital Manometer
PS309
Featured are an integral variable reluctance transducer, solid state electronics module, 3 digit liquid crystal display (LCD)* and battery pack with six 1.5V penlight cells for truly portable operation. The units can also be powered from an external DC power supply or AC battery eliminator (converter) module. The transducer features all corrosion resistant materials in contact with the pressure media (both ports in differential units), very low internal cavity volumes and ultra-low volumetric displacement with full-scale pressure excursion. Transducer calibration is unaffected by dielectric properties of the sensed fluid. Gauge and differential transducers may be disassembled and range changed by simple diaphragm replacement.

Draft Range Trasmitter
DR800
The Validyne Model DR800 Draft Range Transmitter is designed exclusively for very low pressure measurement needs. It has a "true" full-scale range as low as 0.25" H2O, making it ideal for air flow control applications. It can be turned down to 0.1" H2O; higher full-scale ranges to 100" H2O are available. The DR800 offers 0.5% accuracy and an operating temperature range of -20F to +185F. The total combined temperature effects are less than 3%/100F.

Low Pressure Variable Reluctance Sensor
DP45
The Validyne DP45 Very Low Differential Pressure Transducer is designed for extremely low pressure measurement in the order of 1 inch water column. This instrument is used extensively in connection with flow measurements where dynamic response at low flow rates is required. Dynamic line pressure effects are minimized due to the combination of low internal volume, symmetrical construction, and small volumetric displacement inherent in the DP45 design.

Carrier Demodulator with LED Display
CD23/223
The CD23 and CD223 Digital Transducer Indicators are designed for use with variable reluctance and differential transformer transducers. The CD23 accepts input from a single transducer, and the CD223 accepts two switch-selectable inputs, with Zero and Span controls for each input. The indicators provide 5 Vrms, 5 kHz carrier excitation voltage to the transducer(s) and solid state circuitry to amplify, demodulate and filter the transducer output signals. A 3 1/2 digit front panel display is standard, with a 4 1/2 digit display optionally available.

Variable Reluctance Pressure Sensor Capable of Range Changes
DP15
An easy-to-replace pressure-sensing diaphragm maximizes the system's functionality by making pressure measurements from 2.22" H2O to 3200 psi in one compact unit. Rugged and reliable, the DP15 pressure sensor provides superior accuracy for measuring low-pressure liquids and gasses, while it withstands the abuse of field and laboratory testing. The ability to change full scale ranges make the DP15 a very cost effective solution for applications that need different pressure ranges or university labs.

General Purpose Basic Carrier Demodulator
CD15
The CD15 Sine Wave Carrier Demodulator operates with variable reluctance transducers to provide a DC output signal for dynamics as well as steady state measurements. A 5kHz sine wave excitation is applied to the two inductance ratio arms of the transducer and the resulting output is demodulated and amplified using the latest integrated circuit techniques. The DC output is obtained from an active filter circuit and gives a uniform response from steady state to 1000 Hz. The low impedance sine wave excitation allows operation with the transducer located over 1,000 feet from the CD15.
