Reduced-Current Wide-Range Digital Igniter Tester for Explosive Devices

Reduced-Current Digital Ingiter Tester

Those working with explosive devices can have peace of mind with the Alpha 4314 KRC’s redundant fail-safe limiting circuitry that physically prohibits accidental ignition in the event of equipment failure.

7 Test Ranges

Select 4 of 7 test ranges when you order, giving you the ultimate in flexibility no matter what your application

4-Wire Kelvin Inputs

Never worry about lead wire length or contact resistance errors requiring redundant calculations with the Alpha 4314 KRC’s 4-wire Kelvin inputs.

Portable or AC Power

Option AC-115 replaces the battery functionality with continuous isolated AC power.

US Military-Approved

The Alpha 4314 KRC has been approved by the Department of Defense and all branches of the armed services, including special projects use (i.e. Cruise Missle).

Export Data to PC/Printer/Recorder

You can configure your instrument with a BCD or RS-232 interface which enables the Alpha 4314 KRC to communicate data with other devices.

Designed with Fail-Safe Circuitry

Countless critical military, aerospace, and industrial applications utilize squibs and other blasting agents, and it is vital that these devices detonate precisely when required – not sooner, not later, not while testing for continuity integrity.  To guarantee both the readiness of the device and the safety of the technician or engineer, the Alpha 4314 KRC is equipped with redundant, dual fail-safe, current-limiting network circuitry that ensures instrument test currents cannot exceed the specified amount.

Even in the unlikely event of a worst case component failure, the output current limiting network is still in effect.

To certify that this level of safety is included in your instrument, we simulate a worst-case component failure during final testing and include the resulting recorded output current flow with your order.

Accurate, Portable Precision

The Alpha 4314 KRC KRC utilizes a four-wire Kelvin input configuration to eliminate lead wire length and lead contact resistance errors. The units are battery powered with a heavy duty rechargable NiMH (10Ah) pack for portability and line isolation purposes. An AC adaptor battery charger is standard. For added convenience and safety, the Alpha 4314 KRC KRC feature an internal switching configuration which automatically disables the battery charging circuit when in the operate mode. Alternately, all power is removed from the output circuitry when in the off/charging mode.

As with all Valhalla Digital Ohmmeters and Igniter Testers, the Alpha 4314 KRC KRC is available with a host of 4-wire probes and cable sets. Consult the end of this section for complete information on Options and Accessories.

Military-Approved

The 4314 series’ circuitry has been reviewed and approved by a U.S. Government Safety Board and all branches of our armed forces for specific military programs (i.e. Cruise Missile).

Options

RS-232 Serial Interface Capability (NEW)

The interface is isolated to 2.5kV on both power and Data lines and uses iCoupler Technology. Option RS-232 provides a safe way to communicate with the Alpha 4314 KRC via a computer or PLC and allows the transfer of single readings or continuous transmission of data. This interface is for data acquisition only and does not provide range control. See Datasheet for more details.

BCD Capability

For applications requiring data output the Alpha 4314 KRC is available with “BCD.”  Notice that the BCD Option does not interfere or change the FailSafe feature of the instrument.

AC-115 Continuous Isolated AC Power

Replaces battery pack functionality with continuous isolated AC power.
