1.1 Application
The portable digital indicator model 7280 is a universal checking device for instrumentation
examination mechanical components like press, equipment of torque and so on. The employment
takes place in the ranges quality assurance, start-up and process monitoring. By high measuring
rates very fast reactions to the measuring signals are possible. A min./max. memory makes
further areas of application possible for the equipment. A universally configurable data logger
can store measured values up to 15288. By the possibility 10 parameter sets to deposit, are
possible different calibration data such as sensor designation and physical units. Measured
values or logging values can be spent over RS232-/USB interface at a PC or a printer. So that
the measurement chain is traceable, a proprietary calibration certificate can be provided. The
traceability of the calibration exists over the used reference normal.
1. General
1.2 Description
The model 7280 is mobile by battery or accu, can be operated however also with an external
power pack. A high measuring accuracy paired with fast measuring rate, 16 bit A/D converter
and a microprocessor are ensured by the employment by highly precise amplifiers.
The pocket model 7280 support sensors on strain gage basis and active sensors to 10 V /
20 mA. Indicated on the 14 mm high LED main display will the current measured value, on a
second display directly under it can for example the peak value be read off. With the function
tare can be away-tared an existing basis load. For a force measuring chain we recommend to
attach the tension and compression load cell model 8524 to the digital indicator. Depending
upon can be selected between measuring range of 500 N and 200 kN (divides into 9 stages).
The reference measuring chain is completely configures and calibrated.
