Introduction
Overfill protection
Spillage caused by overfilling can be hazardous to people and the environment,
resulting in lost product and potentially high clean-up costs.
High- and low-level alarm
Maximum and minimum level detection in tanks containing different types of
liquids are ideal applications. The Rosemount 2130 is robust and operates
continuously across the process temperature range of –94 to 500 °F (–70 to 260 °C)
and operating pressures of up to 1450 psig (100 barg), making it perfect for use as a
high- or low-level alarm. It is common practice to have an independent high-level
alarm switch as a backup to an installed level device in case of primary failure.
Pump control (limit detection)
Batch processing tanks often contain stirrers and agitators to ensure mixing and
product 'fluidity'.
The standard user selectable time delay, from 0.3 to 30 seconds, virtually eliminates
the risk of false switching from splashing.
Pump protection or empty pipe detection
With the fork projecting only 2 in. (50 mm) (dependent on connection type), the
Rosemount 2130 can be installed in small diameter pipes. Short forks mean
minimum intrusion on the wetside and allow for simple, low cost installation at any
angle into pipes or tanks. By selecting the option of direct load switching or relay
electronics, the Rosemount 2130 is ideal for reliable pump control and can be used
to protect against pumps running dry.
High-temperature applications
The 2130***E version is designed for high temperatures and is suitable for
continuous operation within the process temperature range of –94 to 500 °F (–70
to 260 °C).
Wireless applications
The advent of wireless communications allows process plant managers to save up
to 90% on installation cost compared with wired technologies. More data can be
collected at central locations than has ever been possible before. The Rosemount
2130 can be used with a Rosemount 702 Wireless Discrete Transmitter to enable
these benefits for your applications.
Hygienic applications
With the highly polished forks option providing a surface finish (Ra) better than
0.4 μm, the Rosemount 2130 meets the most stringent hygienic requirements used
in food and beverage, and pharmaceutical applications. It is robust enough to easily
withstand CIP (Clean In Place) and SIP (Steam In Place) cleaning routines.
