The Chell 2401/2402 pressure standards are a one or two channel pressure standard designed to compliment the Chell range of pressure and temperature scanners.

The standards feature a Chell high accuracy pressure standard which gives a measurement accuracy of ±0.02% FS in either absolute or differential mode. This output is available over the Chell standard range of Ethernet output interfaces; Chell native protocol, IENA, modbus and iDDS at speeds up to 100Hz per channel.

For integration into existing facilities, it also features a Netscannner® emulation mode where a significant subset of the Netscanner commands are supported.

In addition to the data output, the 2401/2402 features an in-built web server for configuration and diagnostics.

The 2401/2402 is a single channel device with an absolute pressure measurement channel. The 2402 uses two absolute channels so can measure these directly as two absolute channels or combine them for a single differential channel.

External measurement connections are made via the 5/16-24 SAE ‘O’ ring bosses. This gives the user the flexibility to specify 1/8” or 1/4” double ferrule compression fittings or AS205 quick disconnects.

The 2401/2402 has a smart power supply which is compatible with a DC supply and PoE. The 2401 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 2401/2402 is fully compatible with iDDS installations.
