INTRODUCTION

myPCProbe is either a temperature sensor (TEMP model) or a temperature and humidity sensor (RHT model) that
features an USB interface for communication with your PC. It is the ideal instrument for monitoring and recording lab
data from teaching, research and industry settings. It is supplied with an Windows application that enables the instant
visualization of logged data in display, bar, gauge or chart formats. The application provides history data logging of
myPCProbe readings, offering resources to visualize data graphically and to export them in different formats. The PC
USB port is accessed as a virtual serial port, which enables compliance with SCADA software that support Modbus RTU
serial communication, or any other application that supports ASCII serial communication.

Multiple modules can be installed, one at each USB port, thus making it easier to increase the number of inputs.
myPCLab application can communicate simultaneously with all installed sensors.

This guide brings the installation and module connection instructions. For information on myPCLab use instructions,
refer to the online Help.

●

Ambient temperature channel: Internal thermistor.

● Built-in cold junction compensation for thermocouples and wire resistance for Pt100.

● Total accuracy:

Thermocouple K: ± 4.5°C (when maximum resolution is selected);
Pt100: ± 1.5°C (when maximum resolution is selected);
Ambient Temperature Channel: ± 1.5°C (20 minutes after connection to the USB port)

Note: It is possible to reduce (and even cut out) errors if after calibration the calibration points are
transferred to the device using the custom calibration screen (via software).

● A/D resolution: Configurable from 15 to 11 bits.

● Sampling rate: 8 to 128 samples per second, depending on resolution and number of channels enabled.

RHT Model (temperature and relative humidity)

● Maximum measurement range: -20 to 100ºC and 0 to 100% RH (available also as dew point). See Figure 04
“Humidity sensor operating conditions”.

● Dimensions: See Figure 03.

Figure 03 - RHT model dimensions

● Accuracy: See Figure 04.
Note: It is possible to reduce (and even cut out) errors if after calibration the calibration points are

transferred to the device using the custom calibration screen (via software).

Electromagnetic compatibility: EN 50081-2, EN 50082-2.
ABS case.

TESTS

This section shows the step response of some myPCProbe models to humidity (RHT model) and temperature (TEMP
model).

RHT MODEL

The myPCProbe-RHT was taken from an extremely dry environment and placed in an extremely wet environment.

Response time (0 to 90%) = 07 min 45 s

TEMP MODEL

In these tests, a calibration furnace was used to provide the required final temperature. Basal temperature was room
temperature (around 25ºC; 77 ºF).

150 x 3 mm probe, thermocouple K
Features: See model number 2 in Table 01.
Probe inserted 130 mm in the furnace.

Response time (0 to 90%) = 2 min 12 s
