The Chell 2432 is another step forward in Chell’s long line of pressure scanners optimised for test cell use. The 2432 makes use of high accuracy digital absolute transducers to give unparalleled performance – even in the most demanding environments. 

The Chell 2432 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 400Hz per channel. It also features a Netscannner emulation mode where a subset of the Netscanner commands are supported to facilitate their use in existing installations. 

The Chell 2432 incorporates an electrically driven shuttle valve for purge and re-zero – therefore removing the need for high pressure supply lines associated with previous versions. 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 with the Chell SQDC range which are durable, high temperature quick disconnects. These are compatible with both flexible and solid tubes. The calibration, reference and purge connections are via 5/16-24 SAE ‘O’ ring boss which can be fitted with Swagelok® or Chell AS series quick disconnects. 

The Chell 2432 incorporates an internal purge control valve to switch the purge gas on and to vent it before the valve is returned to run. 

The 2432 has a smart power supply which is compatible with a DC supply and PoE. The 2432 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 2432 is fully compatible with iDDS installations.
