Analog Ammeter/Power Meter BLOW 94995 – 15 A with Shunt

The BLOW 94995 Analog Ammeter/Power Meter is a panel-mounted instrument designed to measure current up to 15 A and to indicate power using an integrated shunt. The instrument features an analog needle display that provides continuous, real-time readings suitable for monitoring electrical loads in control panels, workshops, and basic test setups. The device is compatible with systems where shunt-based measurement is appropriate and is intended for installation in environments that require visual, immediate indication of current and derived power.

Advantages

The analog needle display offers quick, easy-to-read real-time indication without the need for digital processing. Built-in shunt enables direct measurement of current and the resulting power calculation without requiring separate external shunt components. The panel-mount format provides straightforward installation into standard control housings and distribution boards. Mechanical design and simple operation make the instrument suitable for routine monitoring and where a robust, low-complexity meter is preferred.

Suitable for

• Monitoring load current in control panels and switchboards
• Workshop and laboratory bench testing where visual current indication is needed
• Basic power monitoring in DC or AC systems when shunt-based measurement is applicable
• Retrofit installations to replace or supplement existing analog instrumentation

Key specifications

• Measurement range: up to 15 A (amperes)
• Display type: analog pointer (needle) indication
• Shunt: integrated shunt for current sensing and power calculation
• Mounting: panel-mount design for control panels and enclosures
• Application: suitable for DC and AC systems where shunt measurement is valid

How to use

Install the meter into a compatible panel cutout and secure it according to the panel-mount dimensions. Connect the meter’s input to the circuit under test following standard electrical wiring practices, ensuring correct polarity and secure connections to the integrated shunt. Power and measurement wiring must comply with applicable safety standards and the system voltage/current limits. Once installed, the analog needle will indicate the instantaneous current and, based on the shunt, provide information for power assessment. Periodically inspect terminals and mechanical fastening to ensure reliable operation.

Usage recommendations

Use the meter within its specified current range and avoid subjecting it to overloads beyond 15 A. Ensure that connections are tight and that the device is mounted in an environment free from excessive vibration, moisture, and corrosive substances. For more accurate power calculations in AC systems, verify that the measurement method (shunt-based) and phase conditions are appropriate for the intended application.
