The LM34CAZ is ideal for cold-junction compensation(CJC) temperature measurements. Customers who are using thermocouples on an external CB37 terminal board can wire this sensor to a nearby analog input, and correlate the CJC offset within software. Simply connect +Vs to LabJack VS, GND to LabJack GND, and Vout to a LabJack AIN terminal (FIO/EIO is best on the U3). It has a very convenient output of 10mV per °F, so 0.78V would correspond with 78°F.

TO-92 Package
Typical Accuracy ±0.4°F
Operating Range 0°F to +230°F (-17 to +110 °C) when powered by 0/5 volts.
Output Voltage 10mV/°F
See LM34 Datasheet for Complete Specifications

The LM34CAZ is the most accurate version of the LM34 precision temperature sensor made by Texas Instruments; it is not manufactured by LabJack, so the LM34 datasheet is hosted by Texas Instruments. Some soldering may be necessary to add length to the sensor wires. For more details about this sensor and a detailed look at different kinds of temperature sensors, see our temperature sensor app note.

How about the LM35?

Note that even if you want to measure in Celsius, the LM34 is better than the LM35 because you get more voltage per temperature (18 mV/°C versus 10 mV/°C) and you can measure lower with a single supply (-17 °C versus +1 °C).

Price:

$119.00

Provides 16 industry standard relay module sockets to a LabJack U12. Image shows RB16 with standard and miniature modules installed. The RB16 provides a versatile method for electricians, engineers, and other qualified individuals, to interface a LabJack U12 with high voltages/currents.

I/O modules are available from a variety of manufacturers such as Grayhill, Crydom, or Kyoto, and allow the LabJack U12 to control or monitor 120/240 VAC and/or 3-60 VDC. The following Grayhill modules are available for purchase from Digikey: 70M-OAC5 (AC output), 70M-ODC5 (DC output), 70M-IAC5 (AC input), 70M-IDC5 (DC input).

Relay modules are NOT included
Modules are available with voltage ratings up to 200 VDC or 280 VAC, and current ratings up to 3.5 amps
DB25 cable is included
Made by Electronic Innovations Corp.
LabJack U12 only. See the RB12 for other devices

Note: The user can also install a resistor to bypass each socket and pass through the standard digital I/O line.
