The TSI Transducer Display & Monitor provides a scaleable digital display for transducers with current or voltage outputs. The monitor's variable time constant controls the response time of the display. High and low alarms can indicate readings outside of a user-defined range. These alarms can be audible, visual and/or remote via relay contacts. The Trasducer Display & Monitor also provides 500 mA of unregulated 23 VDC power to operate your trasducer. The microprocessor-based design providesibility through menu-driven, field selectable options including signal input, full scale reading, time constant and alarm levels.

The Transducer Display & Monitor Model 8495 is an ideal accessory for TSI's Air Velocity Transducers, providing flexibity in outputs while also powering the transducer. The adjustable full scale reading allows you to scale the display to fit your application. For example, if mounting the transducer in a duct, you can select a full scale reading that includes a multiplication factor to convert to units of volumetric flow rate or even mass flow rate. The span adjustment can be used as a density correction factor, allowing you to correct the readings for changes in temperature or pressure. When using an air velocity transducer in a fluctuating flow, increasing the variable time constant will provide a more stable display of velocity or flow. If monitoring velocity or flow in a critical process application, using the high and low alarms will indicate readings outside of an acceptable range.

The accuracy for Model 8455 is ±2.0 percent of reading ±0.5 percent of full-scale. The accuracy is the sum of the two components of the specifications.Example: If you have a Model 8455 with a full-scale range of 4,000 ft/min and an output of 0-5 volts and it reads 4.0 V (or 3,200 ft/min) the accuracy is calculated as follows: ±0.5% of reading ±0.5% of full scale = ±0.02(3,200 ft/min) ±0.005(4,000 ft/min) = ±64 ft/min ±20 ft/min, The total accuracy is the then equal to ±84 ft/min or 2.6% at 3,200 ft/min.

Transducer offers field-selectable velocity range, time constant, output signal, and input power.Probe length of 3 inches (75mm) must be specified at the time an order is placed.

No. The analog output from the transducer is a continuous linear output in 0-5V, 0-10V, 1-5V, 2-10V, 0-20 mA, or 4-20 mA depending on how it is set by the user. It is field-selectable and changeable.

The transducer is returned to TSI for calibration to be performed in a laser-verified wind tunnel. The calibration information is programmed into an EPROM and the typical turnaround is one week for any recalibration or service.

The transducer makes single-point readings. For multi-point readings, additional transducers must be purchased.

Yes, as long as they are connected in parallel for units with voltage output and in series for current output. The resistance of all output indicators in series cannot exceed 270 Ohms on a unit with a current output.
