Filled System Thermometers

Filled system thermometers

Filled system
Choice of case size (100 or 150 mm) and material.  All stainless steel temperature systems.  Non-Toxic “Filsafe” filling medium.  Temperature indication and control at low cost.  Clear design - easy to read.  Easy to install.  Maintenance free: reliable under the most arduous conditions.  Instruments tailor-made for customer’s applications.  Can be supplied with a choice of thermowells.  With similar filling options the famous “Clearway” range of thermometers offers a robust and corrosion resistant fibre glass case.  Most models in the range may be specified with electrical contact heads to provide alarm or control function.  Clearway temperature indicator controllers can be specified with built in relay and regulator versions and are are available for switching heavier loads.  Special models are available for diesel exhaust applications. Rototherm filled system thermometers are designed to give guaranteed reliability over a wide range of ambient temperature conditions and are compensated for temperature changes from -30 to +50ºC.  The filled system range of thermometers are tough yet accurate instruments with rigid stems for direct mounting or with flexible capillary for remote reading.  Two case styles and case sizes are available in both rigid stem and flexible capillary formats.  The Stainless Steel cased range of thermometers can be specified with either mercury or the more popular “filsafe” non toxic filling medium.

Diesel Exhaust Thermometers

The Rototherm range of diesel exhaust thermometers provide and an accurate and reliable indication of the exhaust gas temperature of diesel engines and generators.

The stem is fitted with a unique anti resonant section which damps out vibration of the instrument head, and eliminates the need for oil filling. The use of the capillary type enables all the dials to be located on a single panel to provide immediate visual comparison of the performance of each cylinder.

Technically advanced features in design, coupled with strict quality control results in a thoroughly dependable instrument which is widely accepted for Naval service throughout the world.

Quality control complies with Ministry of Defence assurance requirement specified in Defence Standard AQAP 4.
