GD52A: Wireless transmitter for 4-wire RTD temperature probes
The GD52A is a wireless GenII transmitter from Eltek for temperature measurement with RTD probes. It accepts two 4-wire RTD (resistance temperature detector) inputs and transmits their readings wirelessly into the Darca Solutions Suite, bringing precise temperature monitoring into one connected view.
How it works
Two 4-wire RTD inputs. Wireless data link.
The GD52A connects two 4-wire RTD probes to a wireless monitoring network. The 4-wire connection is the method used to remove lead-resistance error from a resistance temperature measurement, which is why it suits precise temperature work.
Readings transmit wirelessly to Darca Command, so RTD measurements sit alongside the rest of your monitored conditions in one dashboard, logged continuously rather than read by hand.
As a GenII transmitter, the GD52A works within the full Darca Solutions Suite through your site's SRV450 hub.
It suits life sciences monitoring and manufacturing and industrial monitoring, wherever precise RTD temperature needs continuous logging. Our complete guide to temperature monitoring sets out the wider approach.

Questions about the GD52A
Frequently asked questions
What is the GD52A?
The GD52A is a wireless GenII transmitter from Eltek that accepts two 4-wire RTD temperature probes and transmits their readings wirelessly into the Darca Solutions Suite.
What is a 4-wire RTD?
An RTD is a resistance temperature detector. A 4-wire connection removes lead-resistance error from the measurement, which is why it is used for precise temperature work.
How many inputs does the GD52A have?
The GD52A has two 4-wire RTD inputs.
Is the GD52A a wireless device?
Yes. The GD52A is a wireless GenII transmitter; the RTD probes connect to the unit by wire and the data link to the network is wireless.
Part of the Darca Solutions Suite
The GD52A is a GenII wireless transmitter in the Darca Collect layer. Readings flow through your site's connectivity hardware to Darca Command — the same cloud platform that manages all your other Eltek sensors, alarms, and compliance records.
Eltek has deployed more than 40,000 GenII wireless transmitters in field worldwide. Four decades of UK engineering. Since 1985.
