The Altek
Model 311A has been designed to calibrate every type of
RTD monitoring and measuring device. The enhanced
circuitry of the 311A makes it compatible with a wider
variety of instruments than other RTD calibrators.
Some newer process control equipment use a pulsed
excitation current to measure RTD sensors. This includes
some smart transmitters, multi-channel recorders and
inputs to programmable logic controllers (PLCs),
computers and digital control systems.
The Model 311A is designed to work with these devices
and accepts intermittent current pulses as short as 10
milliseconds. It calibrates devices with excitation
currents of as little as 0.090 mA and as high as 10.20
mA
Altek’s Model 311A RTD Calibrator lets you SIMULATE and
READ RTDs over the entire industrial temperature range.
Switch between four platinum 100 ranges and two ranges
each for copper and nickel.
Simulate RTD resistances into all types of measuring
instruments. The Altek Model 311A takes the place of
bulky, expensive decade boxes and temperature tables.
Output directly in °C, °F* or dial in the resistance
value in ohms.
Save time with every calibration by instantly recalling
three output settings for each RTD type with the handy
Quik-Chek switch. All output settings are remembered,
even with the power off.
The Model 311A display gives you fast, accurate
temperature measurement with 0.1° and 1° or resistance
measurement to 500.00 ohms with 0.01 ohm resolution.
Two, three and four wire hookups assure accuracy in long
cable runs. Open RTDs and leads are detected and
indicated on the LCD display. Two readings per second
track fast moving temperatures.
"MAX" and "MIN" memories are continuously updated from
turn-on or whenever the "RESET" button is pressed. Model
311A gives you a handy tool to monitor temperatures for
drift or control deviation. Just flip the Quik-Chek
switch to display the minimum and maximum temperature
measured since reset. |
