Ram Meter Inc. - April 2020 Newsletter

April 8th, 2020:
We have just released our April 2020 Newsletter. Read on to see what we have in store this month. Or checkout the full version online HERE!

This month we are proud to introduce the addition of a brand new product line to our mix - SENVA SENSORS!

Senva is a fast growing manufacturer of various types of sensors, energy meters and remote LED displays. Some people believe they're successful because of their innovative, customer inspired products. Others lean towards their Made in the USA quality. Another contingent swears by their service and dedicated employees.

We'll let you in on a little secret - it's all of the above!

Senva EM-RS485 Protocol Energy Meter

The Senva EM-RS485 is the safest and fastest meter to install on the market. It is the perfect product for retrofits as the high voltage components are embedded in the Current/Voltage Transducer™ (CVT™). The entire assembly is easily mounted inside the electrical panel, eliminating labor and space required to install a separate transducer box. Each CVT™ sensor uses digital communication with the meter for superior noise immunity - ideal for applications where accuracy matters! The CVT™ sensors are individually calibrated and measurement accuracy is independent of the transducer.

The EM-RS485 is a three channel meter, capable of monitoring single-phase, two-phase and three-phase systems, as well as 3 independent single-phase systems with one meter. The EM-RS485 meter offers BACnet MS/TP and Modbus RTU protocols and 2 pulse inputs to maintain flexibility during installation and operation. The EM-RS485 is compatible with all sizes of CVT's™. With the EM-RS485 intelligent meter technology, the device self-configures baud rate, serial format, protocol, and address (BACnet only) - eliminating additional configuration steps. One universal EM-RS485 meter supports all CVT™ sensor options (sold separately) in the family.

Features:

  • 0.2% Meter Accuracy (ANSI C12.20 Class 0.2 standards), 1% System (meter + CVT™) Accuracy
  • Auto-configures baud rate, network type, serial format and self-addresses - No manual configuration necessary during install
  • Supports both BACnet MS/TP and Modbus RTU
  • Self diagnosing meter for troubleshooting assistance
  • 2 pulse inputs for connecting other meters (water, gas, steam, etc.)
  • One universal meter supports all CVT™ sensor options (sold separately) in the family
  • All CVT's™ (sold separately) sizes rated for 90-600V
  • Calibration is at the CVT™ level so any CVT™ from the family will maintain its accuracy with any EM Series meter
  • Multiple mounting options
    • Supports mounting on either horizontal or vertical PR30 (TS 35/F6) DIN rail
    • Snap-in mounting ears allow screwing to any suitable surface
    • Integrated rare earth magenets secures the EM-RS485 meter to any ferrous enclosure or surface - ideal for auditing!
  • Compact Size - fits in the palm of your hand!

Senva CVT Rogowski Coil Flexible Current Transformers

The Senva Rogowski Coil Current/Voltage Transducer™ (CVT™) measures both voltage and current, communicating the data digitally to the meter via plug-in low voltage connections. This allows the meter to remain a low voltage device. Each CVT™ uses digital communication with the meter for superior noise immunity. The CVTs™ are individually calibrated and measurement accuracy is independent of the transducer. To complement the CVT™, the Senva metering platform offers two meter options (EM-PULSE & EM-RS485) which are small enough to fit in the palm of your hand, yet powerful enough to self-configure during installation, removing all manual configuration. Virtually a plug and play BACnet meter!

The Senva CVTs™ are best used with the Senva EM-RS485 Energy Meter (see above)

Features:

  • Digitally calibrated CVTs™ are extremely accurate
  • The accuracy is as high as a calibrated system, yet different CVTs™ can be changed from meter to meter and the accuracy is maintained. A big advantage for auditing, since your meter is not size specific
  • Plug and play installation— individual CVTs™ are digitally recognized by the meter base and outputs are automatically scaled—no user set up is required
  • Digital communication offers superior noise immunity compared to traditional induced low signal Rogowski Coils
  • All the high voltage connections are at the CVT™
  • Rogowski CVTs™ are available in 4 sizes from 9” to 36” in circumference and include several rating options from 300A to 6000A and are universally rated for 90-600V

Senva C-2345 Adjustable Split-Core AC Current Transformer

The Senva C-2345 is a split-core transducer which measures AC current and provides a proportional output for load trending and control. The C-2345 features selectable ranges to make scaling easy and to reduce inventory levels while the optional command relay (sold separately) makes this an extremely versatile transducer, all at a very low, affordable cost. Ideal for Load Trending, Motor Control, Process Control, Fan/Pump Status, Motor Load Jamming and Lighting Load Level applications.

Features:

  • C-2345 = 0-30/60/120 ACA /4-20 DCmA
  • Window Size = 0.75" x 0.75"
  • Split-Core Design
  • Selectable ranges makes scaling easy and reduces inventory
  • Mount sensor without removing conductor for installation savings
  • Clamp on conductor with iris or use detachable base to screw or DIN mount
  • Larger 0.75” aperture accommodates oversize conductors
  • Reliable and cost-effective
  • Industry leading 7 year limited warranty

Senva C-1220HV Mini Solid-Core Adjustable AC Current Transducer

The Senva C-1220HV is a solid-core AC current transducer which allows for matching sensor set-point to the motor nameplate, eliminating the need to calibrate in energized enclosures and reducing installation time. It will detect motor undercurrent conditions such as belt loss, coupling shear, and mechanical failure on fans and pumps.

Features:

  • C-1220HV = 0-50 ACA / 0-120 ACV
  • Window Size = 0.30"
  • Solid-Core Design
  • Adjustable input
  • Preset™ scaled calibration enables set-point adjustment for proof of flow by simply matching dial to motor full load amps (FLA) nameplate
  • Safer: Eliminates calibration in energized enclosures, reduces arc flash hazard
  • No need to return to calibrate—saves time and money
  • Super low turn-on
  • Superior to differential pressure sensors
  • Industry leading 7 year warranty

DID YOU KNOW?

Did you know that Ram Meter Inc. offers Custom Instrumentation for both the analog and digital panel meters that we sell? Our analog & digital panel meters are offered with industry standard input ranges and scaling values. These include ranges such as 0-30 Volts AC, 0-50 Amps DC, 0-5 Amps AC, etc. with scale values such as 0-50, 0-75, 0-100, 0-150, 0-200 and so on. Many of these standard input ranges and scales can be found in the Panel Meters & Instrumentation section of our website.

But not every application is "standard". At Ram Meter Inc. we understand that every application is different and can sometimes require custom input ranges/scales. Maybe you would like colored arcs or even a company logo displayed.
