Control and instrumentation

Control

Watlow controller with Hanse ChamberCore software: temperature, humidity and GRMS ramps in one profile over Ethernet

ChamberDAQ

24 universal inputs on each Watlow F4T (thermocouple, RTD, mA, mV/V), with more F4Ts for more inputs, plus up to eight WebDAQ modules for 128 external thermocouple channels

ChamberFFT (option)

Vibration analysis on up to 16 IEPE accelerometer channels at 25,600 samples per second

Accelerometer

One accelerometer with cable and three-axis mounting block

Safety

Door interlocks

Opening a door shuts off system operation

Emergency power off

EPO shuts off system operation

Over/under limit

FM-approved, with its own sensor in the air stream

Interlocks

Heaters and LN2 interlocked to the fans; three-phase supply monitored for phase loss and balance

Electrical code

Built to NEC code with UL / CE marked components

Options

• Extended temperature — down to −150 °C and up to +400 °C, as an option or custom build.
• Humidity — direct water injection or a steam generator, 10 to 85% RH from 25 to 65 °C, with a capacitance sensor.
• Fixtures — designed for your assembly, with metric or inch hole patterns.
• More channels — specify at order; channels are far cheaper than a retrofit.
• Access ports — extra ports, 6 in or custom sizes, for cabling and powered functional test.
• Higher load capacity — available across the range.
• LN2 system — complete installation, piping and controls.

Warranty and support

• 3-year warranty on vibrators and vibration tables.
• 1-year equipment warranty from shipment: parts and labor for the first 90 days, then parts at no cost other than travel.
• Supported for the long term — including controller retrofits for older systems.
