Das TEMP 120 ist ein Modul speziell zur Messung von Thermoelementen. Es hat 20 Eingangskanäle mit Miniatur-Buchsen zum Anschluss verschiedener Thermoelemente. Das TEMP 120 kann unter extreme Umweltbedingungen arbeiten und auch schnelle Temperaturänderungen sind kein Problem. Es hat eine eingebaute Referenztemperatur für jeden Eingangskanal und ist speziell entwickelt, um Messfehler gerade beim Auftreten von externen Temperaturgradienten zu minimieren.

Technische Beschreibung

The inputs of the TEMP 120 are a universal copper-copper junction and can accept any standard thermocouple alloy type. The TEMP 120 is part of a data acquisition system that includes a data logger such as a GRANITE 6/9/10, CR6, or CR1000X. The clock timing synchronization across modules is managed by the data logger via the CPI communication port. The time base can be referenced either to GPS or a temperature-compensated real-time clock in the data logger. Applications requiring hundreds of terminals of thermocouples can be easily assembled as a single data acquisition system. Measurement modules can be collocated or spread out via a networking cable to be closer to the point of measurement.
