7200系列

1个-半 "国产储罐的 MPT 仪表

Application
The 7200 and B7200 Series Junior™ gauges are identical except the former has a zinc die-cast head and the latter has a forged-brass head. Both types have 1 ¼” Male NPTF threads and 2” [51] hex-wrenching sections and are equipped with direct-reading dials appropriate for the tanks in which they are installed.

General Information & Features*
Model 7281 and B7281 direct-indicating gauges are for top mounting. When used on above-ground ASME, horizontal, domestic storage tanks, they are equipped with 5323S01749 percentage or 5323S01789 fractional dials. When used on tanks buried underground, they are equipped 5323S01813 percentage dials. Most 420# [190kg] vertical cylinders utilize the 5323S01835 dial. For dials used on other vertical cylinders, contact Rochester.

7284型和 B7284 型仪表用于侧面、端部或角度安装。当在 ASME 电机油箱上使用时, 它们配备了5323S017889 分数表盘。有关安装在升舱卡车气缸上的仪表上使用的各种表盘的部件号, 请联系罗切斯特。

7241型 (顶部安装) 和7241型 (侧端或角度安装) 仪表采用了更强的磁铁, 可在电机燃料应用中驱动 Twinstene™发送器。这些仪表可提供较低的表盘与5323S01789 分数, 直接指示拨号或与适当的 TwinSite™发送者, P5628S0537, 0-90ω, 或 p5663s0257 20-150Ω (根据需要)。
