IHA 500 The precision pressure indicator IKA 500 is equipped with up to two modular precision sensors (in two separate channels) and an optional barometric reference. Due to an optionally certified measurement inaccuracy of 0.01 % FS, differential pressure of ± 0.03 % FS of the entire measuring chain, it is primarily used as transfer / working standard for the testing resp. calibration of diverse pressure measuring instruments. A colour touch screen and intuitive navigation ensure very easy operation. Especially with manual pressure generation, the very high measuring rate of this fully digital pressure indicator is of advantage, as pressure changes in the measuring system are indicated nearly in real time. Besides the optionally available calibration software DCal, which allows for comfortable calibration of pressure measuring instruments, including automatic creation of test certificates, the user is able to create own software programmes. For integration in existing systems an RS-232, Ethernet or optionally an IEEE-488.2 interface or an analogue output 4 - 20 mA are available. Completely mobile or stationary test equipment can be manufactured upon request. - APPLICATIONS Laboratories Service industries and calibration services Research and development Transmitter calibration Long-term measurement HIGHLIGHTS Accuracy up to 0.008 % FS Internal precision sensors possible 6 digits resolution Modular design Approx. 10 ms of response time barometric reference is required for the change of absolute pressure <=> gauge pressure 800 mbar to 1,200 mbar abs. 0.01% FS (Optional 0.008 % FS (optional) 23 and 1 freely programmable desktop case optional: 19” rack mounting with side panels incl. mounting kit approx. 2.0 kg (4.41 lb) 6 digits 1 line per sensor colour touch screen approx. 10 ms amount of assimilable sensors 1 (channel A) or optionally 2 (channel B)
