To record different types of input signals, signal attenuation and amplification options are available for the STARLOG Data Logger.
Our selection includes Signal Amplifiers, Special Interfaces, Voltage Dividers, Current Loop References and other Special Purpose Modules.
Signal conditioning equipment is typically soldered onto a Field Termination Strip, becoming part of the on-site installation.
NOTE: The Signal Amplifier modules are not applicable to the MACRO and Starlog PROLOGGER data loggers which have inbuilt signal amplification (see Order Information box for details).
Low level signals may be measured by the Data Logger using a signal amplifier. These low power instrumentation amplifiers are small circuit board modules which mount perpendicular to the Field Termination Strip, adjacent to the associated input channel. Provision is made for up to eight modules.
Each signal amplifier module reduces the Logger battery’s life: e.g., when five modules are installed, a battery operates for 10% less time than its estimated life.
||For unipolar or bipolar signals ±4.5V single ended or differential thermocouples (STARLOGGER only)
||For signals which are measured relative to the Data Logger common (ground)
||For signals which are not referenced to ground but are between 0.5 and 4.5 volts offset from ground (e.g., strain gauge input)
||For signals which are not referenced to ground (over 4.5 volts offset from ground) and where isolation is required
||For K-type thermocouples only – to measure temperatures in the range of 0 to 255°C.
