SHPFI-M

Glenn — Sat, 17 Feb 2018 22:16:28 +0000

The SHPFI-M is a smart frequency to current converter and also a frequency to frequency pulse scaler. It is intended to be used with flow meters and similar devices who generate a pulse signal either from a magnetic pickup or a contact closure whose frequency is related to flow rate and where each pulse represents a quantity of flow. The SHPFI-M also contains a linearization function commonly required by flow meters to improve their accuracy. The flow rate and total are computed within the SHPFI-M and the 4-20mA analog output and the high level scaled pulse output are generated from these computed values. The SHPFI-M is programmed using a special setup program from a PC. A special programming cable called the BSAC1 is also required. These items are purchased separately. The computed Rate and Total may also be viewed on your PC using these special cables.

AMP-2

The KEP AMP-2 is a two channel amplifier for use with magnetic pickups. It amplifies and squares the low level signals from a magnetic pickup to drive any ratemeter, totalizer or controller. The unit operates from 8.5 to 30 VDC. It has a 10K pullup resistor attached to the open collector output and sinks a minimum of 20 mA to less than 1 V from a maximum of 30 VDC. It is available in OEM (PC board only), NEMA4X enclosure or in a rugged explosion proof housing with screw terminals for easy installation. Operating temperature is -40° to 65°C.

Note: The low voltage line from the magnetic pickup to the AMP-2 should be less than 10 ft. in length, shielded and isolated from relays, solenoids or other sources of electrical noise (let the output line make the long run). If the input is too sensitive, lower the 10K input impedance by adding a 1K ohm resistor across TB1, pins 1 and 2, 4 and 5 to increase noise immunity.

The KEP AMP-1-N powers and conditions the low level signals from NAMUR pickups, sensing gear teeth movement or flow, and provides a high level pulse output suitable to drive any KEP ratemeter, counter or controller.

AMP1 & AMP1-10K

The KEP AMP 1 amplifies the low level signals from a magnetic pickup or flow transmitter by a factor of more than a hundred times to drive any ratemeter, counter or controller. The unit uses only 30 mA and operates from 11 to 26 VDC. It has a 2.7K pullup resistor attached to the open collector output and sinks a minimum of 100 mA to less than 1 V from a maximum of 26 VDC. It is mounted in a rugged 2″ x 3″ metal housing with screw terminals for easy installation. Operating temperature is 32 to 140° F (0 to 60° C).

A special version, the AMP1-10k, is available with 10 kΩ impedance for use with turbine and paddle wheel flowmeters.

MS-817 (MS817)

Glenn — Sat, 17 Feb 2018 22:01:20 +0000

The model MS817 is a signal conditioner which permits the user to condition and scale the input pulses from a pulse producing sensor into a high level output where each pulse represents an engineering unit of measure.

Several pulse input types are supported including magnetic pickup, contact closure, and an isolated pulse input.

SC-IF (SCIF)

The SC-IF is a loop powered signal conditioner whose function is to provide a 0 – 10kHz frequency output signal in response to a 4- 20mA analog input. The SC-IF appears to the input loop as a series shunt resistor. A small sense resistor is used to measure the input current. The input loop derives it’s power from the input current loop.

The model SC-FF is a signal conditioner which permits the user to condition and scale the input pulses from a pulse producing sensor into a high level output where each pulse represents an engineering unit of measure. Several pulse input types are supported including magnetic pickup, contact closure, and an isolated pulse input.

SC-II (SCII)

The SC-II loop powered isolator is a signal conditioner whose function is to provide a retransmitted, galvanically isolated 4-20 mA output signal in response to isolated 4-20 analog input. The loop powered isolator may be applied in a similar manner as a conventional two wire transmitter.

SC-FI (SCFI)

Glenn — Sat, 17 Feb 2018 19:47:15 +0000

The SC-FI Signal Conditioner is a two wire frequency to analog converter that converts a pulse rate input into a 4-20 mA output signal proportional to frequency or rate. The input pulse rate is amplified and filtered by the input signal conditioning circuitry. Two forms of input signal conditioning are provided, one for magnetic pickups or contact closure inputs and the other is an isolated pulse input (depending on order code).
