Accessories for digital panel meters

You can add value to your digital panel meter and large display installations with these useful accessories.

Splashproof Covers - SPC4

Upgrade to IP67/NEMA4X protection for the front panel of all your 1/8 DIN panel meters with these splashproof covers. Unlike similar versions you'll find on the market, these have a completely non-ferrous, high-impact frame, to give long life.

They'll always look clean and won't rust, because we use stainless materials which cope with wet corrosive atmospheres.

Wall Mounting Cases

If you want to wall-mount a panel meter, and need IP65 protection, these enclosures fit the bill perfectly. You can choose versions which hold one or two meters or bargraph displays. Rust free, high impact resistant thermoplastic for long, trouble-free life in the harshest conditions.

Temperature & Humidity transmitters

Ideal for monitoring temperature and humidity in production environments. Choose either 2 x 4-20mA output or RS485 Modbus RTU output.



Key points :-

1. Wide range suits most industries
2. Analogue or serial outputs
3. Choice of filters for the sensor
4. Rugged, reliable, smart.




The LEL18 transducer is for the continuous measurement and conversion of relative humidity and ambient temperature into a digital or analogue voltage or current standard signal. The transducer may be programmmed and calibrated through the RS-485 interface.

Sensor shields allow the transducer to operate in various ambient conditions, dusty, dry, corrosive etc.. The transducer is designed to be mounted on a wall.

The LEL18 transducer performs following functions:

• calculation of selected physical quantities, (dew-point temperature, absolute humidity)
• conversion of measured quantities into a linear output signal
• memory of maximum and minimum values for each value
• programming of the measurement averaging time
• servicing of RS-485 interface in MODBUS RTU mode.

Technical Data
Basic parameters:
- relative humidity measurement (RH) 0...100% without condensation
- basic error +/- 2% for rh 10...90% +/- 3% for remaining range
- hysteresis for humidity measurement +/- 1%
- temperature measurement range (T) - 30...85oC
- temperature conversion accuracy +/- 0.5% of the range
- calculates abs. humidity (a) [g/m3] dew-point temp. (Td) [oC]
- additional errors: temp. effect +/- 25% of basic error/10oC

Signal Selector switches

If you want to monitor a number of measurements, one at a time, these selector switches are ideal.

All are 1/8DIN format. They have detachable screw connectors and high performance, low thermal EMF contacts.

For 4-20ma signals, we even include loop-continuity zener diodes, so your loops stay continuous at all times.

Models include...

• 3 pole 12 way for PT100
• 2 pole 8 way with zener diodes for 4-20mA
• 2 pole 8 way with BCD output to signal which position is active

Laboratory Bench Cases

If you want a meter for a local measurement, but don't have a control panel to mount it in, the PCC series of portable carrying cases is ideal. Built to your needs, they come fully wired, with all the connectors you'll need and a plug-in IEC power cable.

Alarm Acceptance Module

Add useful features to your existing alarm system.
