  • This meter has been designed specifically for RPM measurements. Just enter the pulses per revolution and the DL-40RPM meter will calculate and display the RPM reading
  • Three ranges with resolutions of 0.1 RPM, 1 RPM and 10 RPM (99.99 X 1000 RPM max.)
  • Optional isolated 16 bit analog output. User or factory scalable to 4 to 20 mA, 0 to 20 mA or 0 to 10 V across any desired digital span from one count to the full scale range of 9999
  • 24 V DC excitation is available to power external sensors
  • Auto-sensing AC/DC power supply. For voltages between 85-265 VAC / 95-370 V DC (PS1) or 15-48 V AC / 10-72 V DC (PS2)
  • Standard red or optional green or super bright red 4-digit LED
  • Red or green 0.8” LED large display option
  • Four annunciator LEDs provide front panel alarm status indication for up to four setpoints
  • Optional relays. Two 10 Amp Form C and two 5 Amp Form A relay, or optionally four 5 Amp Form A relays are available


Texmate’s DL-40RPM series are smart programmable, speed measurement ,relay meter with 4 to 20 mA retransmission or control loop output capability for measurement and control applications.
These unique members of the Leopard family is available with IF05 Plug-in Modular Input Signal Conditioner for RPM measurement .

An optional NEMA-4 dust and water proof lens cover with a keylock is available. ideal for harsh environments or to secure the meter from unauthorized access.

The meter’s plastic case is made from fire retardant polycarbonate and a metal surround case can be ordered to enhance the meter’s fire retardant capabilities and also provide shielding against electromagnetic interference (EMI).

n.b. Special meter inputs can be factory scaled.
