Door Tester Unit ZTA-RDM-2000N

Measuring range 0 - 2000 N

Digital force gauge for determination of closing forces of automatic doors according DIN EN 12445, DIN EN 12650 and JISA4721

High quality force measuring unit with interface (RS-232, analog and USB and memory). This device has a fast measuring frequency for exact acquisition of peak values.

Force gauge with separate remote load sensor

CE mark

Special Features

2 operation modes:
real time – display the actual tension or compression force
peak force – to measure the peak force during a test

Door tester unit ZTA-RDM-2000N with extremely high sampling rate of 2000 times/sec for fast acquisition of peak values

Display update time 10 times/sec

Easy to read display (OLED)

The header and footer of the display can be customized, as well as switched on and off

Programmable high/low set-points for go/no-go testing:
with color-coded LED display: underrun (-NG) – good (OK) – exceeding (+NG) and relay outputs

Storage of 1000 values, which can be recalled:
– on the display
– data transfer to a PC
– for printing with report

Output signal:
– RS 232 C for connecting to a PC
– analog ±2 V DC
– Mitutoyo Digimatic e. g. to print the readings on a printer

Display can be reversed for inverted use; e. g. on vertical test stand

»Zero Set« to zero the gauge in all operating positions

Force gauge with user switchable units: N, kgf (gf) und lbf (ozf)

Selectable language (english, german, italian, french, spanish, chinese, japanese, korean)

Manufacturers inspection certificate is included

Special features in comparison to standard unit ZTS-RDM-2000N

Readings can be saved on a USB flash drive (Not included in delivery).

2 high/low output values can be set; If the reading reaches one of the output values, data will be sent to external devices (e.g. PC, printer) for data recording

Indication of two peak values per measurement.
