Siemens 151726-70 Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Siemens 151726-70 is a precision pressure switch engineered for the continuous monitoring of gas or air pressure in combustion plants. It utilizes a highly sensitive diaphragm mechanism to detect minute pressure fluctuations, triggering a safety interlock if the pressure drops below or exceeds predefined critical thresholds. Essential for industrial gas burners, forced draft systems, and ventilation equipment, the 151726-70 prevents unsafe ignition attempts or operation during gas supply failures or combustion air loss. The QPL/QPD series is valued for its accurate setpoint adjustment, high repeatability, and rugged design, ensuring the fundamental safety prerequisites of the combustion process are always met.
