OVERVIEW:
The MT-190 Magnetic Trigger Sensor has an Amplifier Module that enhances the performance of the M-190W Magnetic Sensor. The
Amplifier extends the operating gap to 0.25 inches [6.35 mm] from the ferrous target. The MT-190 Magnetic Trigger Sensor with Amplifier
can sense gear teeth, bolt heads or shaft keys. The MT-190 provides a pulsed output signal and is TTL compatible with 5 Vdc supplied.
The MT-190 has an 8 foot [2.438 m] cable with 3 tinned wires (MT-190W) or 1/8 [3.5 mm] phone plug (MT-190P) termination.
The MT-190W is compatible with all Monarch ACT Series panel tachometers and Data-Chart 1250 Paperless Recorders.
The MT-190P is compatible with the following Monarch instruments: Pocket Laser Tachometer 200 (PLT200), SPSR Self-Powered
Sensor, Deluxe Nova-Strobe x Series (dbx and dax) and Phaser-Strobe pbx.
The MT-190W and MT-190P can also output pulses to a user’s data acquisition system.
CONNECTION DETAIL:
The Magnetic Sensor must be connected to the Magnetic Trigger
Amplifier Module. Refer to Figure 2 for connection detail. The
connection details for the Amplifier Module are shown below Figure 2.
When using the MT-190W with any Monarch instrument, refer to the
instrument instruction manual for sensor connection detail.
When using the MT-190P with any Monarch instrument, plug the 1/8
[3.5 mm] phone plug into the input jack on the respective instrument.
When using the Amplifier Module with the GE-200 Gasoline Engine
Sensor, the 15 foot [4.572 m] MX-005 cable is connected to the OM-200
sensor and then the BNC end of the MX-005 cable is connected to the
BNC connector on the Magnetic Trigger Amplifier Module.
OPERATION:
Magnetic sensors convert motion of a ferrous target into an AC voltage
output proportional to speed. The Amplifer Module converts the signal
to pulses. The target must not be smaller than the magnetic poll piece
(0.106 inches, 2.692 mm) or larger than the diameter of the sensor (0.625
inches, 15.875 mm). Gear teeth are preferred, but bolt heads, slots or
keys also work. The Monarch ACT Series panel tachometers will
typically operate from all 2-wire design magnetic sensors. The stainless
steel and waterproof housing of the M-190W sensor allow operation in harsh locations. The user can increase the cable length up to a total
of 500 feet [152.4 m] in length.
