Supported Applications
The Omega CYC325 Series, including models CYC325, CYC325-T1, and CYC325-T2, is a precision cryogenic temperature controller designed for controlling and measuring temperatures in laboratory and industrial environments. The instrument features a front panel with a digital display and keypad for setup and operation.
Per manufacturer warnings, the equipment is not intended to be used as a 'Basic Component' under 10 CFR 21 (NRC) in nuclear installations or activities, nor is it intended for medical applications or use on humans.
Operating Conditions & Performance
The series operates within an ambient temperature range of 0 °C to 50 °C and supports a process measurement range from 1.5 K to 400 K, with optional sensors available for extended ranges. The instrument provides a resolution of 0.001 K.
- Accuracy: ±0.05% of reading or ±0.05 K, whichever is greater; improved to ±0.01% of reading or ±0.01 K with CalCurve™.
- Response Time: Typical 10 seconds (depends on system thermal mass).
- Humidity Rating: 0% to 90% RH, non-condensing.
- Storage Temperature: -40 °C to 70 °C.
The unit is housed in a metal chassis with a plastic front panel and carries an enclosure rating of NEMA 1. It complies with the European EMC Directive 89/336/EEC as a Class A product (CE Mark).
Configuration Options
The CYC325 Series is configurable for various control and monitoring needs through selectable outputs, excitation currents, and optional accessories.
- Output Signals: 0-20 mA (load resistance 0 to 500 Ω), 4-20 mA, 0-10 V, 0-5 V, or Relay Output.
- Excitation Current: Selectable between 10 µA or 1 mA.
- Power Supply: 100-240 VAC, 50/60 Hz with rear panel connectors for sensor inputs, heater outputs, and power via screw terminals.
- Dimensions (W x H x D): 193 mm x 127 mm x 305 mm; weight is approximately 4.5 kg.
- Options & Accessories: Optional sensors for extended range, calibration services, and software for remote control and data logging are available.
Key Product Differences
The series includes specific model designations: CYC325, CYC325-T1, and CYC325-T2. The manual notes that the full list of accessories is not explicitly detailed beyond general mentions.
Users should note EMC considerations for Class A products in domestic environments; radio interference may occur requiring adequate measures by the user. Additionally, improper cabling installation may defeat EMC protection, and warranty coverage excludes damage from tampering, excessive corrosion, current, heat, moisture, vibration, or misuse outside of Omega's control.
