General Purpose Pressure Transducer and Transmitter
P55
The robust P55 pressure transducer provides cost-effective reliability for severe test environments. With extreme resistance to shock and vibration, the P55 pressure transducer delivers the same high-level performance expected from more delicate differential pressure transducers and pressure transmitters. With variable reluctance sensing technology, the P55 pressure transducer delivers fast dynamic response, high resistance to vibration and superior signal stability through ambient temperature change for a wide variety of low-pressure to high-pressure measurements. The P55 pressure transducer will accept both liquids and gases directly at the sensing diaphragm and there are no internal isolation fluids to slow the sensor response or cause excessive temperature drift errors.

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.

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.

Variable Reluctance Absolute Pressure Sensor
AP10
The AP10, Absolute Pressure Sensor, is designed for low and medium pressure measurements, to laboratory accuracy, of corrosive liquids and gases. In typical AC excited bridge circuits, this transducer delivers a full-scale output of 40 mV per volt at 3kHz. The unit operates with carrier systems including the Validyne CD15 sine wave carrier demodulator and CD16 miniature DC input DC output carrier demodulator to produce a high level analog DC output suitable for recording and control.

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.

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.

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.

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.
