Plug-in sensors

EasySense Q is supplied with:
2 plug-in temperature sensors and
#
Two long sensor leads.
#
Plug-in sensors connect to the two inputs on
EasySense Q labelled as 1A and 2B. When a sensor
is connected it will automatically be detected and
displayed on the LCD screen (in Meters) as number 1)
and/or 2) (depending on which input the sensor is
connected to). The plug-in sensor inputs are dual
labelled as A and B because the Timer software is
specified in these terms.
The plug-in temperature sensors
Plug the temperature sensor into one of the external
inputs on the back of EasySense Q (labelled 1A or
2B) with the locating arrow facing upwards.
EasySense Q will automatically detect that a
temperature sensor is connected and display
temperature values in degrees Celsius.
The plug-in temperature sensors are supplied calibrated with a range of -30 to 110ºC.
Temperature measurements are taken by a thermistor, which is housed at the tip of a
stainless steel tube. The stainless steel tube is made from AISI 316 stainless steel,
which has a particularly low thermal inertia with a negligible effect on the measured
temperature. It provides a high level of resistance to corrosion from a wide variety of
weak acids and alkalis, making it suitable for use with experiments in chemistry, biology,
physics, earth and environmental science.
See page 17 for further practical information about the temperature sensor.
The Sensor leads
Two long sensors leads have been provided for use with Smart Q sensors that are
available to purchase separately and are not supplied with EasySense Q.
Smart Q sensors can be divided into two main types:
1. Analogue – which are used to measure
physical quantities such as temperature,
sound, light, pH, etc.
2. Digital - which are switch-type sensors
for measuring ON/OFF conditions such
as light gates and timing mats used for
calculating time, speed and accelertion.

date list of Smart Q Sensors.
