Instrumentation for SRU's

 The E2T Pulsar 4 is an explosion‑proof infrared thermometer (pyrometer) designed for high‑temperature petrochemical applications like sulfur reactors and furnaces. It continuously measures process temperature in a harsh, hazardous environment and sends a stable 4–20 mA signal back to the control system, helping operators protect refractory, monitor combustion, and keep critical equipment running within safe limits. 

 The E2T Pulsar 4 Advanced is an explosion‑proof infrared thermometer for demanding refinery and petrochemical service on SRUs It builds on Pulsar 4 with diagnostics and an FMA (Flame Measurement Algorithm) for truer gas temperature through flame. HART‑compatible 4–20 mA output delivers temperatures to the control room, helping operators protect refractory, control combustion, and respond sooner to changes that threaten runtime and equipment life. 

 The retractable thermocouple is a high‑temperature sensor assembly for refinery and petrochemical service on reactors, heaters, and process lines. It allows insertion, adjustment, and removal of the sensing element without breaking process containment, using a packing gland and isolation valve. This design supports accurate, repeatable temperature measurements while simplifying maintenance and reducing downtime on critical equipment.
