OMEGA Engineering, Inc. Temperature Meter DP460-T

The DP460 Series is designed for a variety of temperature, current, voltage, strain gage and load cell measuring applications. Excellent accuracy and small size combine to make it the ideal choice for most industrial indications. The DP460-T and DP460-RTD temperature measurement models feature a unique 0.1 or 1 automatic resolution (unless the instrument is programmed to display 1 only).This temperature meter is selectable among nine temperature sensors or thermocouple types, J, K, T, E, R, S, and B or 100 ohm; 3- wire, Platinum RTD's for either .00385 or .00392 alpha. Behind the snap-off lens, each of these nine thermocouples can be selected via a miniature rotary switch. No calibration is required to switch between thermocouple types. Another miniature DIP switch selects between F or C display. The DP460-V voltage models allow selection between mA or voltage input with a switch easily accessible behind the snap-off front lens. Full scales are 0 to 20 mA or 0 to 10 V. These or any subset ( e.g., 4 to 20 mA, 1 to 5 V) can be scaled. Two simple pushbuttons conveniently located behind the snap-off lens are used to set zero (Lo), full scale (Hi) and a decimal point. The indicator can be scaled within its wide -999 to 9999 display count. The DP460-S strain gage models are compatible with both bonded-foil type (2 mV/V, 3 mV/V, 4 mV/V) transducers and higher output, semiconductor (10 mV/V, 20 mV/V, 30 mV/V) type strain gages. Its microprocessor design and ratiometric measuring circuit assure high accuracy with superior repeatability. Scaling and calibrating the DP460-S to display engineering units from the strain gage input is similar to the DP460- V models. There are no pots to drift nor complicated formulas to compute to set DIP switch gain ranges. It can achieve sensitivities as low as 1 V per count and can be scaled anywhere within its wide -999 to 9999 display count.
