For dynamic thermal environments.
Designed to expand and contract during dynamic thermal conditions, these steam/water gages have extraheavy construction incorporating a wide chamber. Thermally induced gage stresses are absorbed by the linear expansion within the stuffing box or the expansion loop. TSL stuffing box or TSL-F flanged configurations can be used for steam/water service at or below 650 psig [4480 kPa]. TSM stuffing box or TSM-F flanged configurations can be used at or below 1500 psig [10340 kPa] steam/water service. Mica shields and Belleville washers are standard to improve the long term sealing of the gage. All materials conform to ASME/ASTM specifications. The following gagecocks are suggested for use with steam/water gages: Model 730 OS&Y- for Model TSL and TSM gage having flanged gage connections; Model 780 OS&Y- for Model TSL and TSM gage having stuffing box connections.
