Task I. Give Ukrainian equivalents to the following word - combinations:
a household furnace, a mercury switch, a home security system, to detect intrusion, a target
internal food temperature, a float, engine rotational speed and vehicle linear speed, "Steam
gauges", sophisticated suite of sensors, avionics systems, redundant, to aid mishap
investigations, throttle position, pneumatic domains, environmental robustness and frequency
response, invariably.

Task II. Read the texts and translate s into Ukrainian:

Household
A very simple example of an instrumentation system is a mechanical thermostat, used
to control a household furnace and thus to control room temperature. A typical unit senses
temperature with a bi-metallic strip. It displays temperature by a needle on the free end of the
strip. It activates the furnace by a mercury switch. As the switch is rotated by the strip, the
mercury makes physical (and thus electrical) contact between electrodes.
Another example of an instrumentation system is a home security system. Such a
system consists of sensors (motion detection, switches to detect door openings), simple
algorithms to detect intrusion, local control (arm/disarm) and remote monitoring of the system
so that the police can be summoned. Communication is an inherent part of the design.
Kitchen appliances use sensors for control. A refrigerator maintains a constant
temperature by measuring the internal temperature. A microwave oven sometimes cooks via a
heat-sense cycle until sensing done. An automatic ice machine makes ice until a limitswitch is
thrown. Pop-up bread toasters can operate by time or by heat measurements. Some ovens use
a temperature probe to cook until a target internal food temperature is reached. A common
toilet refills the water tank until a float closes the valve. The float is acting as a water level
sensor.
Modern automobiles have complex instrumentation. In addition to displays of engine
rotational speed and vehicle linear speed, there are also displays of battery voltage and
