Model TD1
Brand: MagnetrolThermatel® TD1 switch can easily be adjusted to detect flow (gases and liquids), level or liquid-liquid interface.
The TD1 is a 24 V DC line powered unit with integral electronics and a built-in DPDT relay.
With continuous diagnostics, automatic temperature compensation, narrow hysteresis and fast response time, the TD1 brings you the latest in thermal dispersion technology.
Features- Easy field calibration – pre-calibration from factory at request.
- Variable flow or Flow/No flow detection of gases and liquids.
- Excellent low flow sensitivity.
- Automatic temperature compensation for repeatable alarm under varying process temperatures.
- Continuous diagnostics detect sensor fault.
- Continuous monitoring of flow rate versus setpoint via
- LED (TD2).
- mA output provides repeatable indication of flow rate and fault detection (TD2).
- Flow can be measured over test points (TD2).
- Optional retractable fitting for dismantling under process conditions.
- Process conditions up to +450 °C (+850 °F) and 414 bar (6000 psi).
- Integral or remote electronics up to 150 m (500 ft).
- Unique spherical tip design option ideal for liquids or high viscosity applications.
- Suited for SIL1 and SIL2 loops (full FMEDA report available).
