Universal Input Meter (Budget - 4 Digit)
Digital Panel Meters process and display values from a given input signal, including voltage, current and resistance. Input sensors measure temperature, pressure, or other variables. Spectra offers a wide range of digital panel meters that represent excellent value for money with high specifications at a low cost.
Spectra has a whole host of LED Displays and Signs to suit your requirements; check out the rest of our Industrial LED Displays.
The Tracker 211 is a universal input digital panel meter and was designed for low cost "no frills" applications. It can be directly connected to most popular process sensors including 20mA loop transmitters, DC signals up to 100mV and 10V, thermocouples and RTDs.
4-20mA, 0-100mV and 0-10V DC signals can be scaled to engineering units using any portion of the -1999 to 9999 display range. Temperature can be displayed in °C or °F to 0.1 degree resolution.
An isolated 24V DC sensor excitation is provided as standard to supply power for 2-wire 4-20mA sensors. In addition, a regulated 10V DC output is provided for strain gauge type sensors such as pressure transducers and load cells.
1 alarm relay is fitted as standard with up to 2 more as options. Setpoints can be adjusted using the hidden buttons behind the front panel or if the setpoints are to be adjusted frequently then the optional button front panel can be fitted.
The measured value can be transmitted as a linear 4-20mA signal to other devices such as chart recorders or data loggers. The output can be scaled to any portion of the display range.
- Low cost
- Universal input for mA, mV, V, thermocouples and RTDs
- 10V and 24V sensor excitation
- 1 alarm relay fitted as standard
- Front panel sealed to IP65
