DESCRIPTION
Thermatel® TG1/TG2 switches consist of electronics in a DIN rail housing and a remote sensor with aluminium or stainless steel sensor housing (max 500 m (1640 ft) away from electronics).
TG1/TG2 switches can easily be adjusted to detect flow (gases and liquids), level or liquid-liquid interface. Both units are 2-wire 24 V DC powered and intrinsically safe approved.
The TG1 offers standard LED flow indication, the TG2 offers LED flow indication per NAMUR NE 44.
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.
- Continuous diagnostics detect sensor fault.
- Continuous monitoring of flow rate versus setpoint via LED.
- mA output provides repeatable indication of flow rate and fault detection.
- Optional retractable fitting for dismantling under process conditions.
- Process conditions up to +450 °C (+850 °F) and 414 bar (6000 psi).
- Unique spherical tip design option ideal for liquids or high viscosity applications.
- Suited for SIL1 and SIL2 loops (full FMEDA report available).
Application
- MEDIA: all types of gases and liquids
- VESSELS: pipe sizes down to 1/4". Max sensor length up to 3,3 m. Can be installed at any angle vertically/horizontally.
- CONDITIONS: Can be used on conductive and non conductive media, very light density to heavy viscous media (up to 10.000 cP). Can be set to ignore foam, aeration, turbulence, and cavitation.
