Temperature Sensor Boards
DMS-30PC/LCD-0 Meters
Description: The DMS-EB-HTB Application Boards accept inputs from user-
supplied, AD590 solid-state temperature sensors. The boards can be used with
any of DATEL's ±200mV, 5V-powered DMS-30PC/LCD-0 Series, 3½ Digit, LED/
LCD Display, Digital Panel Voltmeters — although better performance can be
achieved with either LCD or low-power LED models. This meter/board combination
provides extremely accurate (±0.3°C) temperature measurements over the range
of –55 to +150°C(with DMS-EB-HTBC) or –67 to +199.9°F (DMS-EB-HTBF).
Individual reference-adjust and probe-adjust potentiometers allow for "fine tuning"
the AD590 output to precisely match the selected meter. A 6-wire, screw-type
terminal block provides for quick, reliable, signal and power connections.
Calibration: R4 (Reference Adjust) is factory-calibrated to +459.8mV for °F
and +273.2mV for °C (do not readjust). This measurement is taken between TB1
(pin 6) and pin 12 of the DMS-30PC/LCD-0. R1 (Probe Adjust) requires customer
adjustment since every sensor has a slightly different zero offset. Calibration is
simple: connect the sensor leads to TB1 and adjust R1 until the DMS-30's display
matches a selected reference temperature indicator.
