WIKA Model 73 Gas-actuated thermometer
$125.00
The WIKA Model 73 gas-actuated thermometer is a precision temperature measuring instrument utilizing gas-filled system technology for industrial applications. This reliable thermometer features a remote reading capability through its flexible capillary system, allowing installation at distances from the measurement point. The gas-actuated principle ensures accurate and stable temperature indications without requiring electrical power. With robust construction and vibration resistance, the Model 73 is ideal for machinery, hydraulic systems, and process plants where reliable temperature monitoring is essential. Its maintenance-free operation and long service life make it suitable for demanding industrial environments.
Description
The model 73 gas-actuated thermometer has been
developed and is manufactured in accordance with the
EN 13190 standard. This high-quality thermometer has been designed especially for the requirements of the process industry. The thermometer, completely manufactured from stainless steel, is used particularly successfully in the chemical and petrochemical, oil and gas, and power engineering industries.
To allow optimum fitting to the process, individual insertion lengths and process connections are available. The thermometers have a high ingress protection of IP65 and can be used in outdoor applications even at negative
temperatures. With liquid damping operation under high
vibration conditions is possible. Due to the wide variety of
possible designs, the model 73 gas-actuated thermometers
can be perfectly adapted to any process connection or
location.
