This unit has a wide voltage range (5-277V AC/DC) and appropriate shock (55g) and vibration (25g)resistance, as well at a 95% relative humidity tolerance. Contact us with any questions or for a quote on these items.
We are now able to supply hour meters and battery indicators for the automotive industry. There are a variety of units available, with LCD and electromechanical displays, with different housing options, dual channel units with hour/hour, count/count, and hour/count configurations. The battery indicators are available with and without an hour meter as well. The meters are available with screw in mounting, bracketed mounting, and pc board mounting with manual reset, external reset, or no reset options. IP-65 rated, hermetically sealed units available to keep out dirt, dust, water and other similar elements. The units are vibration resistant.
All meters come with a 1 year warranty, and are competitively priced for OEM’s. If you have any questions about these meters please feel free to contact us.

Vehicle vacuum & pressure tester. Low cost sensor usually requires offset (zero) and Gain (span) adjustment.
Precision vacuum and low pressure adjustments require a digital readout. Low cost sensors may have large offset (up to +/- 10%) and span (up to +/- 5%) errors. Sensors are usually able to measure a vacuum as well as pressure.
A +/-30 to +30 psi sensor with a 4 to 20 mA output is easily handled by the DPL-3. Since vacuum is most usually measured in this range, it is advantageous to optimize the calibration for vacuum. The best way is to calibrate the meter to read -30.0 with the sensor at 30 psi of vacuum and to display 00.0 with the sensor exposed to ambient (0 psi gage) pressure. The positive or pressure readings will be within the linearity of the pressure sensor.
The ‘PSI’ annunciator can also be enabled on the DPL-3 display.
DPV and DPL Meters Simplify Readout in Units Measured
- Convert to display of actual units measured. E.g.. 12 mA or 3 V input can be set to display 900 gallons.
- Single stocked meter can cover multiple applications.
- Negative and positive display from single polarity signal.
- Eliminate need for offset (zero) circuits.
- Direct readout from Transmitters & Transducers.
- Eliminate external circuit adjustments.
Convert to display of actual units measured. Eg. 12 mA or 3 V input can be set to display 250 gallons (946 liters).
Transmitter outputs are typically set for 4 to 20 mA with 4mA representing the low end of the range and 20 mA representing the high end of the range. For example in an application measuring the volume in a tank, a level transducer transmits 4mA when the tank is empty and transmits 20 mA when the tank is at full capacity of 500 gallons.
This type of transmitter has several benefits in industrial applications such as this one. The ?live zero? of 4 mA indicates the system and ?loop? is functioning. If the signal falls below 4 mA it indicates an open loop or other failure. A current signal is much more immune to electrical noise than a voltage signal, since only a parasitic or leakage current can cause an error. A current signal can be transmitted over longer distances than a voltage as long as the loop supply voltage can handle the voltage drop due to lead resistance.
The DPL-3 Series panel meters can be easily adjusted to read 000 with a 4 mA input and 500 with a 20mA input. Other intermediate inputs such as 8 mA would display a reading of 125 gallons, and 14 mA would display 313 gallons.
If a hose-proof & splash-proof display with larger digits is desired, the DPL-807 can be substituted for the DPL-3 Series . All these LCD meters are powered directly from the 4 to 20 mA signal eliminating the need for additional power supplies and simplifying the connection without requiring supply isolation. If backlighting is desired it can be powered directly from the loop supply and is isolated from the meter.
If the volume is to be displayed in other units, such as liters, the meters can be simply readjusted to display the level in liters. In this example 500 gallons is equivalent to 1893 liters, so the meter would be readjusted to display 1893 with a 20 mA input.
In the event that the converted value was greater than 2000, e.g. 1800 gallons is 6814 liters, a 4 ½ digit 20,000 count meter, the DPL-4, could be substituted for the DPL-3, and adjusted for the higher readings.
Readout in actual psi, bars, or pascals from multiple pressure transducers (voltage or 4 to 20 ma).
A manufacturer of custom pneumatic/hydraulic systems required displays for many different pressures. In advance of an actual order, they did not know what their immediate future requirements would be. They standardized on pressure transducers with 4 to 20 mA outputs, but still required stocking meters with seven different standard ranges from 200 psi to 10,000 psi. Further complicating this, they also were required to display various units of measure such as psi, pascals, bars, etc..
Since each meter usually had to be custom calibrated for them, it seemed production was always waiting for meters, even though they had a very large number of meters in stock.
The solution was simple, they reduced inventory and always had the meter they needed in stock. They stocked only two meters a 3 ½ digit (+/- 2000 count) DPL-3E and a 4 ½ digit (+/- 20,000 count) DPL-4E. The very wide offset (ZERO) and gain (SPAN) adjustment meant they could set them to display any units they required. They did pre-adjust them in the shop using a low cost 4 to 20 mA source, but did the final calibration on the production floor allowing them to match the meter to the transducer and eliminate the transducer span and offset error also. Since the meters can be adjusted at any two points, 0 pressure being an obvious choice for one of the points, they did not have to over pressure the system, just make the adjustments at their regular tests points.
Besides reducing inventory, and improving production flow, there was the added benefit of a significant cost savings per meter from their previous source. Part of this cost savings was reinvested in standardizing on the stunning blue backlit DPL-3EB and DPL-4EB meters, thus enhancing their product’s overall appearance.
A further benefit was these meters come with a ‘PSI’ annunciator on the display which they could turn on when the pressure measurement was displayed in psi.
