------Question for PAXT0010 Please Put your question below------
I see that this is programmable, however the purpose needed is to read off an existing probe that has a resistance of 10k(due to length). Can this device be adjusted for this resistance to give a temp between -10 to 35 degrees Celsius? Data connection may also be needed.
Welcome to DigiKey TechForum and thanks for your inquiry.
The PAXT0010 is a programmable panel meter by Red Lion that supports several input types:
Thermocouple (T, J, K, etc.)
RTD (Pt100, Ni120, Cu10)
Voltage and current inputs
Resistance input range: 0–400 Ω
Your Application: 10 kΩ Probe (due to length)
The meter’s resistance input range is limited to 0–400 Ω, so it cannot directly handle a 10 kΩ probe.
A 10 kΩ resistance corresponds to an RTD far outside its supported range, so you cannot calibrate the meter to read −10 °C to +35 °C using that probe directly.
What You Can Do
To achieve your goal, you’ll need one of the following:
Signal Conditioning (Scaling)
Use a resistor divider or buffer to scale your 10 kΩ signal into the 0–400 Ω input range.
External Transducer / Amplifier
Convert the 10 kΩ resistance (from your probe) to a standard 4–20 mA or 0–10 V signal that the PAXT0010 can directly read.
Upgrade Input Card
Add an analog output option card (e.g., current/voltage) that interprets the probe externally, and feed its output to the meter.
Summary
Meter input capability: up to 400 Ω only
10 kΩ probe: not directly supported
Recommendation: use a conditioner or transducer to convert the 10 kΩ resistance into a compatible signal (e.g., 0–400 Ω, 4–20 mA, or 0–10 V)
Your Application: 10 kΩ Probe (due to length)
