Temperature Measurement
|
|
The Series 460 measures and displays accurate temperatures reliably and repeatedly. Sensor input types are selectable from a smooth, environmentally protected front panel keypad. Choose either Model 460, a 4-digit resolution meter, or Model 461, a higher resolution 5-digit instrument. With either model, you can add a variety of input options to tailor the instrument precisely to your needs. For unmatched repeatability and accuracy, the Series 460 uses a new wide-range, integrating voltage-to-frequency conversion technique. An integral microprocessor generates periodic digital auto-zero readings for baseline verification. Because
temperature sensors emit very low signal levels, RFI and EMI often
present the most serious obstacle to accurate readings. The Series 460
common mode rejection ratio exceeds 120dB, ensuring rejection of
unwanted common mode voltages from ground loops that would otherwise
make measurements unreliable. Outputs are also shielded, preserving data
integrity all the way to your readout or printout. |

Series 460 Options |
| Tailor
the instruments with options to extend your measurement capabilities.
Five option slots are available in each meter. The following options can
be specified now, or added at any time in the future.
Multiple Inputs: Monitor as many as 24 inputs. The first multiple input card switches six channels of thermocouples or three channels of RTD or thermistor units. Maximum of 4 cards per instrument. Order Option: -20 (6 inputs of thermocouple); -21 (3 inputs of RTD/thermistor). Math Expressions: Provides display of maximum, minimum, rate of change or timed average value of measurements. Front panel keys allow you to view the math value or switch back to view the actual measured value. Order Option: -04 Alarms: Each option card provides two alarms with separate limits and relays. Up to two cards can be specified. Any combination of high, low or ± values can be used to trigger the alarm, from either actual or math processed input. Trigger delay and a settable dead-band are included as standard. Order Option: -03 (order two for 4 alarms) Analog Output: For output to recorders or other analog input instruments, you can choose from two fully isolated, linearized analog outputs. Both output types, 4-20mA or 0-10VDC can be fully scaled. Output can be assigned to direct measurements or to math values. Order Option: -06 (4-20mA); -05 (0-10VDC) Digital Output: Serial Output RS232C or 20mA interface sends display information in serial ASCII format. Includes user selectable transmission rates from 300 to 9600 baud, line feed, and carriage return. Order Option: -07 IEEE-488 Output. For integration with IEEE-488 Bus based measurement or analytical systems. Main indicator and other options can be programmed via the IEEE-488 Bus. (Requires two option slots.) Order Option: -08 Differential measurement. This card provides an additional input channel and the capability to display the difference (sT) between the two channels. This option card, -22, can be specified with thermocouple and voltage input models. The -23 option is specifically for use with RTD or thermistor configurations. This function can
be combined with other options: maximum, minimum, and average deltas
when used with math capability, scaled analog output of differentials
when used with analog output, and alarm points based on differential
limits (Cannot be used in same indicator with -20 and -21 options. Not
for use with current loop or strain-gage versions.) Order Option -22
for DELTA and 2 thermocouple or voltage inputs, -23 for DELTA and 2 RTD
or thermistor inputs. |

Doric provides complete portable thermometry solutions with meters, probes, and accessories. If you're looking for fast response coupled with high repeatability in surface, air, or immersion measurements, you're looking for a Doric handheld thermometer. For maximum performance, pick from among the most accurate, reliable, and convenient handheld thermometers ever developed — the Series 450 from Doric. Using a unique, patented noise-reduction circuit, the Series 450 achieves the high repeatability and accuracy of line-powered bench top units. A custom-designed dual IC set gives you a single instrument with wider temperature ranges, higher resolutions, and longer performance than other handheld thermometers. Data hold freezes the displayed reading for safe viewing away from hazardous measurement locations. Battery life is unsurpassed, with a single nine-volt battery providing more than 2000 hours of use. An externally available zero pot, conveniently located at the back of the instrument, lets you match ice point calibrations to specific probes for even greater system accuracy. The 450s are available in thermocouple, RTD, or thermistor configurations. Please specify when ordering. Model 450K is for use with Type K thermocouple probes and provides the fastest response time over a wide temperature range. Model 450PT is for use with platinum RTDs, which will provide the greatest system accuracy over a wide range. The thermistor version, Model 450TH, is a fixed 0.1 F/ C high-resolution meter and is compatible with thermistor probes that offer high accuracy in a narrow, low-temperature range. Meter versions are also available for use with existing Type J, E, and T thermocouples. For years of
reliable, accurate temperature measurements, get the only handheld
thermometer that measures up to the standards of bench top units — the
Series 450 from Doric. |
