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.

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.

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.

Pressure Sensor Kit for Changing Ranges
DP15TL
The wide range of diaphragms furnished eliminates expensive stocking of several transducers and offers the versatility of the differential type bi-directional transducer at a very low cost. The broad line pressure capability of this unit makes it useful in almost every laboratory application from flow to level measurement, vacuum to 3000 PSIG. The high output, when used with a carrier system such as the Model CD15 Sine Wave Carrier Demodulator or the CD12 Transducer Indicator, provides resolution equal to many secondary standard units.

High Line Pressure Variable Reluctance Pressure Sensor to 10,000 psid
DP360/DP363
The DP360 can be calibrated for a full scale as low as ±50 psid while withstanding high static line pressure. Low differential pressure may be measured at static pressures as high as 10,000 psig with a maximum 3% FS zero shift error.

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.

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.

High Line Pressure Transducer
P365
The P365D transducer is designed to make low differential pressure measurements at high static line pressures. Operating from unregulated 9 to 55Vdc, the P365D is available with 4-20mA, 5Vdc or isolated 5Vdc output over full scale pressure ranges from 8 to 10,000 psid. The output shift due to static pressure will not exceed 3% of full scale, up to a line pressure of 10,000 psig.

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. Contact our Sales Department for a link to the Demo!
