Instrument for non-contact infrared temperature measurement combined with tachometer functions
First Claim
1. A handheld instrument that accomplishes non-contact infrared (IR) temperature measurement and the measurement of movement of an object, comprising:
- a case;
a movement-sensing device coupled to the case and operable to be directed toward or placed against an object being measured, for generating an output signal based on the sensed movement;
an IR detector carried by the case, for sensing IR energy emitted from a surface being measured along an IR-sensing axis that extends from the case, and generating an IR output signal;
means for converting sensed IR energy to a temperature value, and for converting the output signal from the movement-sensing device to at least a measured movement value; and
a display device in the case, for displaying instrument measurements to the user.

Abstract
A handheld instrument that accomplishes non-contact infrared (IR) temperature measurement, and the measurement of movement of an object. The instrument has a case, and a movement-sensing device coupled to the case and operable to be directed toward or placed against an object being measured, for generating an output signal based on the sensed movement. An IR detector, also carried by the case, senses IR energy emitted from a surface being measured along an IR-sensing axis that extends from the case, and generates an IR output signal. The sensed IR energy is converted to a temperature value, and the output signal from the current-sensing device is converted to at least a measured current value. A display device in the case displays instrument measurements to the user.
