Granite Temp 120 20-Channel Thermocouple Module

THÔNG TIN SẢN PHẨM

Overview

The Granite™ Temp 120 is a purpose-built thermocouple measurement module. It has 20 thermocouple inputs using universal-alloy miniature thermocouple jacks. The Temp 120 is made to handle extreme temperature environments and rapid thermal gradients applied to the measurement module. It has a dedicated temperature reference for every input terminal and is carefully designed to reduce temperature errors in the presence of external temperature gradients.

Benefits and Features

Universal-type standard miniature thermocouple connectors
Cold-junction reference temperatures on every channel
Exceptional accuracy and temperature stability
CPI DAQ connection for channel expansion
CAN bus 2.0 A/B output available
USB 2.0 interface for PC-based operation

Detailed Description

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 DAQ such as a Granite 6, 9, or 10, or the CR6 or CR1000X Dataloggers. The clock timing synchronization across modules is managed by the DAQ or data logger via the CPI communication port. The time base can be referenced either to GPS or a temperature-compensated real-time clock. 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.
