张力仪是测量丝网受到拉力作用时其内部与固定丝网接触体之间的相互牵引力大小的仪器。张力仪有机械式和电子式两种，测量张力的单位用牛顿/厘米表示。张力也可以用相对数值来表示。厘米张力仪就是用相对数值表示张力的一种，是通过张力仪自身重量使丝网下沉的深度的数值(毫米)来计算，张力数值可从指示盘上直接得到，或者从控制盘上间接得到。张力仪有手工操作和机械操作两种。张力仪是检验丝网印版质量的重要的检测仪器。为保证得到制版要求的张力，在绷网过程中或绷网后都要使用张力仪测量。

德国施密特（Hans Schmidt & Co GmbH）专注于卷材张力检测和张力控制有超过60年历史，是大张力测量仪表生产商。旗下产品有皮带张力计BD-435适用于更大尺寸材料的张力检测，例如电缆，电线和绳索。

The BD-435 Electronic Tension Meter measures running line tensions during the production of textiles, fibers, tows and tape type material. This convenient one-hａnd operated device incorporates built-in tension sensor, amplifier and display and is fitted with ceramic oxide coated thread guides. Three long, closely-spaced slender shafts with ceramic guides makes the BD 435 particularly suitable for brief, routine tension measurement - even in locations with limited access space.
