Reference listing
This page holds a place in the catalogue structure. The specification shows the indicative figures published for this instrument class so the layout can be reviewed; it does not describe a supplied product. Confirmed values, brand and documentation are issued with the quotation for the model actually sourced.

A panel meter does a small job that is otherwise awkward: it puts a reading where an operator is already standing. Control systems display values remotely, but for local indication at a machine, a pump station or a test bench a panel meter is faster to read and independent of the network.
The two decisions that matter are the input type and the relay configuration. Almost every meter accepts a 4-20 mA signal; far fewer accept a direct RTD or thermocouple without an external transmitter, and buying that capability at the meter is usually cheaper than adding a transmitter later.
Features
- Programmable scaling so the display reads directly in engineering units
- Multi-input design accepting current, voltage, resistance and thermocouple signals
- Relay outputs for local alarm or simple on-off control without a separate controller
- Optional 24 V loop excitation, removing the need for a separate supply
- Retransmitted analog or Modbus output for connection to a control system

Certification and compliance
Certification documents not yet supplied
Certifications are only published once a certificate copy can be produced, so this section is deliberately empty rather than populated with assumed approvals. Tell us which approvals your application requires and we will confirm what is available for this instrument.
Parameters still to be confirmed
The following are required for a complete specification but are not stated in the documentation supplied to us. They are listed rather than estimated:
- Certification list (CE / RoHS / EMC) and availability of certificate copies
- Accuracy reference standard defining the stated accuracy class
- Operating temperature range
- Ingress protection rating of the supplied variant
- Warranty period and the terms that apply
- English-language datasheet and manual in PDF form
- Wiring diagram and terminal definitions
- Packaging dimensions and gross weight for freight calculation
Frequently asked questions
Can it power the loop as well as read it?
Yes, where the 24 V excitation option is fitted. That removes the need for a separate loop supply and is usually the most economical way to add local indication to a two-wire transmitter.
Is a panel meter still needed when the value is on the control system?
It is a convenience, not a requirement, but a local reading is useful during commissioning and troubleshooting, and it stays readable when the network does not.
