Indicator with two process inputs

July 2002 Maintenance, Test & Measurement, Calibration

To meet specialised requirements where two inputs need to be processed together - to add, subtract, divide, multiply or ratio - Digital Process Measurement has designed the Model 4015. Each input is selectable for 0 to 10 V or 0/4 to 20 mA and is separately scaleable. It is possible to display input 1, input 2 or the result.

Examples of applications are adding two separate flows together to derive the total; subtracting one level from another to obtain the difference; multiplying temperature with pressure for steam or air flow indication.

Options available on these DIN 48 x 98 mm LED instruments include 0-5/10 V or 0/4-20 mA retransmission, max 4 setpoints/alarm, galvanic isolated DC supply, parallel BCD, peak hold or RS232 output. The Model 4015 is part of the 4000 range of 4-digit microprocessor indicators which measure and display all process variables such as temperature, pressure, level, flow, DC voltages or currents. As with all internationally distributed panel meters designed and manufactured by Digital Process Measurement, the Model 4015 is produced to ISO 9001 standards, complies with CE requirements and comes with a three-year guarantee.
