Temperature
Standard range is -40°F to 176°F, -40°C to 80°C with optional stainless steel mounting bolts which maybe required for temperatures below -20°F, -29°C.
Accuracy
Accuracy depends upon proper gauge sizing and is typically ±5% of dial indication. Accurancy may be less due to variations in liquid temperature. Accuracy may be less for some tank shapes and sizes. Accuracy may be less near full and empty. Accuracy may be less if tank is not level. This gauge is not to be used for filling. All accuracy estimates are expressed as a percent of full scale.
Shock & Vibration
Suitable for mobile service applications.
Maximum Pressure
375 psig [25,8 Bar]
UL Listing
UL listed for NH3 service.
订购时指定:
1. Gauge head size, Junior or Senior.
2. Tank diameter as shown on nameplate.
3. Mounting location (top, side, end, or angle),
4. If gauge is angle mounted, state degree of angle above or below the horizontal centerline.
5. If gauge is end mounted, state the shape of the tank head, hemispherical or semi-ellipsoidal.
6. the “H” dimension (distance in inches from the surface of the tank to the gasket surface on the riser).
要订购更换仪表, 只需提供在仪表头一侧的一个平面部分上盖章的信息, 如示例所示。
Note: For installation instructions see MS-501/502 (mounting standards).
CAUTION: For applications where NH3 may include small amounts of water or chemical additives, see model A6480 with improved corrosion resistance.
