Differential
Low Differential Pressure Measuremenet

The DP850/851 transmitters are designed for low pressure measurement in HVAC applications. The DP850 is available in full scale pressure ranges as low as 0.25 inH2O and the DP851 can be ranged to 0.025 inH2O full scale. Both models are available in 4-20 mA or 0 to +5 Vdc signal output options.

Gauge & Differential
Low Range, Wet Wet Capability

The P300 D/A Pressure Transducer is designed for direct application in DC strain gage instrumentation systems which require low pressure ranges not generally available in strain gage transducers. Functionally, it is a direct replacement for a strain gage transducer, providing a 5 mV/V nominal DC output over an excitation range of 5 to 12 Vdc.

Gauge & Differential Manometer
Portable and Self Contained Digital Pressure Manometer

The PS309 is a portable, completely self-contained digital pressure manometer, available in absolute, gauge and differential ranges. In addition to the front panel liquid crystal digital display, the unit also provides a 2 Vdc analog output suitable or recording, remote display or control purposes.

Featured are an integral variable reluctance transducer, solid state electronics

Variable Reluctance Transducer & Carrier Demodulator
Integrated Package

The P24 Differential Pressure Transducer is the combination of a variable reluctance pressure transducer and a miniature carrier demodulator integrated into a single package to provide for operation from mobile dc power and deliver a standardized dc output suitable for recording or telemetry.

Draft
Precision Draft Range Measurement

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 -20°F to +185°F. The total combined temperature effects are less than 3%/100°F.

Differential
Digitally Compensated

The Validyne model P855 is a digitally compensated differential pressure transmitter designed for industrial pressure measurement applications. The on-board microprocessor provides high accuracy and improved stability in changing thermal environments. The P855 is designed for a wide variety of low pressure measurements where fast dynamic response, high resistance to vibration and superior signal stability through temperature change is required. The P855 will accept both liquids and gases directly at the sensing diaphragm.

Gauge & Differential
Ultra-Low Range Measurement

Validne’s P532 Pressure Transmitters are ideally suited for measuring extremely low liquid and gas pressures in industrial applications. Full-scale differential pressure ranges from 0.10” H2O to 2” H2O with line pressure rating of 100 psig, and ranges of 2” H2O to 3200 psid with line pressures up to 3200 psig are offered. Gauge pressure ranges start at 0.10” H2O and absolute pressure from 0.08 psia full-scale. This unique design, which utilizes a diaphragm-type variable reluctance pressure sensor, provides many outstanding advantages.

Differential
High Line Pressure

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 ± 5 to ± 10,000 psid. The output shift due to static pressure will not exceed 3% of full scale, up to a line pressure of 12,500 psig.

Differential
Serial interface for Digital Operation

The Validyne model P56 is a digital differential pressure transmitter designed for industrial pressure measurement applications. The on-board microprocessor provides high accuracy and improved stability in changing thermal environments. Communication via RS485 serial interface provides remote zero and span adjustment as well as pressure readings in engineering units. ±5 Vdc or 4-20 mA analog output included.

Gage
General Purpose

Validyne's P2 pressure transducers provide cost effective gage pressure measurement solutions for your industrial applications. With a rugged design and stainless steel wetted parts. The P2 also features superior performance with 0.25% accuracy and temperature compensation.

Differential
Compact Size

The Validyne model P55 is a compact differential pressure transmitter designed for industrial pressure measurement applications. The variable reluctance sensing technology allows the P55 to be used in a wide variety of low pressure measurements where fast dynamic response, high resistance to vibration and superior signal stability through temperature change is required. The P55 will accept both liquids and gases directly at the sensing diaphragm; there are no internal isolation fluids to slow the sensor response or cause temperature drift errors.

Absolute
All Welded

The AP10, Absolute Pressure Transducer, 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.
