Description
The Chell 2416 is a 16 channel industrial pressure scanner. Like the microDAQ products and the 2432, the 2416 makes use of high accuracy digital absolute transducers to give unparalleled performance – even in the most demanding environments.
The 2416 has been designed to give the user all the desirable features of a modern pressure scanner. These include a 3 position electric shuttle valve (no 7 bar air requirement), digital transducers with pressure and temperature measurement per port, simultaneous acquisition across all channels and an unrivalled set of output interfaces to suit most installations.
The Chell 2416 will output differential or absolute temperature compensated engineering unit pressure data over Ethernet with the Chell native protocol, IENA, and iDDS at speeds up to 1kHz per channel.
For integration into existing facilities, it also features a Netscannner emulation mode where a significant subset of the Netscanner commands are supported.
The Chell 2416 incorporates an electrically driven shuttle valve for purge and re-zero – therefore removing the need for high pressure supply lines associated with other scanners. The 2416 will also measure and control the purge gas flow removing the need for external valving. The shuttle valve features positional feedback, current sensing on the motor and a count of the number of shuttles to help with planning maintenance requirements. The valve life is tested to 10,000 cycles.
External measurement connectors are made via the 5/16-24 SAE ‘O’ ring bosses. This gives the user the flexibility to specify 1/8” double ferrule compression fittings or AS205 quick disconnects. In addition, these fitting can be added to two 8-channel quick disconnect plates.
The 2416 is available with an optional software controlled internal heater (no increase in case size). This will increase the internal temperature to 20C when using PoE and 25C when using 28 VDC supply. It is recommended that the internal temperature is above 0C when moving the internal purge/cal valve.
The 2416 has a smart power supply which is compatible with a DC supply and PoE. The 2416 will always use a DC supply if it senses one – otherwise it will negotiate with a PoE enabled switch for power. With the addition of an iDDS run time license, the 2416 is fully compatible with iDDS installations.
