Temperature Monitoring System from Barnant

Temperature Monitoring System from Barnant

• Store and recall up to 4680 sets of readings with time and date

• Automatically or manually display, record and output temperature readings

• Field calibrate each probe separately - achieve accuracies of ± 0.1% of reading!

• Bidirectional RS-232 for setup or PC datalogging

• Includes a real-time clock, nonvolatile memory, and parallel printer output (benchtop only)

• Immune to RF interference

Our Temperature Monitoring System is ideal when simultaneous monitoring of temperatures during different process steps or phases is critical, these new 12-channel scanning thermometers. The wall mount Temperature Monitoring System is ideal for permanent installation and continuous monitoring of your processes. The benchtop Temperature Monitoring System accepts most any power source giving you great flexibility as to where and when it may be used. Both models function as a datalogger - store data in the non-volatile memory and later download to your printer or PC. Link both models in series to expand the number of channels you can scan. Each of the 12 thermocouple inputs are programmable to scan from every four seconds to hourly.

Benchtop Thermometer

Parallel printer connection allows you to connect the thermometer to a printer - make a hard copy of your data as a permanent record

Power unit with included 115 VAC or 230 VAC adapter or any 10 to 25 VDC or 7 to 20 VAC 500 mA power supply. (user supplied)

Accepts thermocouple probes with miniconnectors for quick and easy probe changes.

Wall-Mount Thermometer

Use high and low relays for on/off control; relays are rated at 250 VAC 2A or 2A at 30 VDC resistive.

Features an easy-to-view drip proof housing with all wire connections on bottom.

Power the unit with 100-240 VAC, 50/60Hz

Instrument Features For Both Models

• Scan and log up to 12 thermocouple inputs from any combination of J, K, T, E, N, B, R, and S thermocouple probes.

• Thermocouple type is individually selectable per channel.

• Datalogging feature automatically stores up to 4680 sets of readings.

• Download readings or stored data to your computer.

• Link up to 8 units together to expand channel capacity.

• Sequentially captures temperature data, allowing you to monitor and record process variations - ideal for statistical process control.

• Easy-to-use front panel MENU key lets you program datalogging and print intervals, scan rate, date and time, temperature scale (°F, °C, K, °R), resolution (0.1 or 1°), channels displayed, thermocouple type, and data output parameters.

• Each channel features HOLD, STORE, MAX and MIN (measures maximum and minimum values), RECALL and AVERAGE buttons.

• Calibrate each channel separately at either one or two points to minimize probe offset. Parameter setup and calibration offsets are stored in nonvolatile memory.

• Each scanner is factory calibrated to NIST-traceable standards.

Multiple Safety Features For Both Models

• MENU key lets you select high or low alarm set points for each channel. Easily enable or disable audible alarm and set alarm hysteresis; program for manual or automatic alarm reset.

• Thermocouple inputs are electrically isolated from each other and from data outputs - provides safe and accurate measurements even when probes are exposed to various electrical conditions.

Physical Features For Both Models

• Large 3/4" high, 14-segment, 12-character alphanumeric LCD indicates channel number or name, temperature reading, and temperature units.

• Indicator light warns you of open probes or out-of-range readings.

• Benchtop models accept thermocouple probes with ANSI miniconnectors for quick hookup and changes.

• Wall-mount models accept thermocouple probes with stripped ends.

Computer/Printer Capabilities For Both Models

• Use printing function to send current readings directly to your computer and printer at chosen intervals.

• Vary datalogging and printing intervals from 4 seconds to 99 minutes, 59 seconds.

• Features RS-232 (for both units), and parallel printer output of date and time (benchtop only), channel number and name, and temperature readings in a tabular format.

• Includes RS-232 cable. Parallel printer cable is not included (sold separately)

Remember to order the proper probes for your application. Barnant offers a wide variety of thermocouple probes (J, K, T, E, N, R, S, and B) wire, connectors and other accessories to insure your temperature scanner will provide the ultimate of function and performance.
